Hi can you help me with multiplying fractions?

Question

I am doing a quiz, it is 10 questions long and I am in need for your help.
I do not understand multiplying fractions but I do get adding and subtracting so here is the question and if you can please explain it to me in the easiest understandable format as possible, it is really much appreciated!

2/15 x 5/8

Also how do you do it with dividing also?

Answer 1

2/15 x 5/8=1/12

you times to two top halves (numerators) of the fractions together so its 2 x 5 =10. (this is the top half of the answer).

you then times the two bottom halves(denominators) together so its 15 x 8 =120 (this is the bottom half of the answer)

you are now left with 10/120. If you want to cancel it down into a simpler fraction you find the highest common factor. (A number that can be divided in to both 10 and 120).In this case it is 10.

So you divide the top half by 10
10 divided by 10 = 1

and the bottom half by 10
120 divided by 10 =12

so the answer is 1/12.

Dividing is similar except you swop the second fraction round.
eg. 1/12 divided by 5/8 =

1/12 x 8/5 (you swop the top and bottom half round, and then times them.)

so the answer would be
8/60
cancel it down and it'll be
2/15

hope this helped

Answer 2

multiply top lines(numerator)and bottom lines(denominator)
2/15x5/8= 2x5/15x8 =10/120 then cancel =1/12

divide turn the second fraction (divisor) upside down and then multiply as above
eg2/15 divide by 5/8 = 2/15 x8/5

Answer 3

multiply straight across, top times top, bottom times bottom--2x5 over 15x8-10/120 or reduced 1/12. to divide, invert the SECOND fraction (8/5) then multiply

Answer 4

i'm useful you will p.c.. somebody else for superb answer. yet i'm giving it a shot! examine this thoroughly and heavily. Multiplying fractions is the least perplexing. seem right here: 2/15x 5/8 this suggests that multliply the proper extensive type by way of the proper extensive type and the backside extensive type by way of the backside extensive type. it incredibly is 10/a hundred and twenty. Now you shrink this. the least perplexing way for me is to divide the proper extensive type and backside extensive type for splendid plausible extensive type that they the two have in undemanding. it incredibly is 10. the answer to this question is one million/12. you spot, 10 divided by way of 10 = one million ; the proper extensive type. a hundred and twenty divided by way of 10 is 12. whilst dividing fractions. in simple terms mulitiply by way of the reciprocal (the FIRIST fraction interior the subject is flipped, enable's say the 1st fraction became 2/3, in simple terms turn it, now it incredibly is 3/2.) Then multiply by way of that reciprocal by way of the 2nd fraction. That' tutor you divide fractions. whilst dividing entire numbers AND fractions consisting of one million one million/2. do exactly 2x1+one million. right here is the answer: You do the backside extensive type cases the full extensive type plus the proper extensive type. remember this. the respond may be 3/2; protecting the backside numbers a similar. it incredibly is termed an incorrect FRACTION. remember this besides. right here is yet another one: Convert 3 2/3 to an incorrect fraction. We do what I reported: backside extensive type cases entire extensive type plus proper extensive type: 3x3+2=eleven. the respond is eleven/3. changing incorrect fractions to Fractions with entire numbers. enable's say a math difficulty instructed you to transform 10/7 to a fraction with an entire extensive type. All you may desire to do is divide the proper extensive type by way of the backside extensive type: 10 divided by way of 7. this is going to be one million 3/7. word that the backside extensive type is often a similar. the the remainder of the branch is often the proper extensive type. There you bypass and sturdy success at your quiz. *the proper extensive type in a fraction is termed the numerator. the backside extensive type is termed the denominator.*
