how to subtract whole number to fraction?example 92-7/15?

Question

to subtract fr.whole no,rename the whole no. to fraction or mixed no.The fraction should be similar to the other fraction......my problem is i dont know how to rename the whole number to make it similar to the other fraction.pllssss kindly xplain.tnx

Answer 1

92 – 7/15
Every integer can be written in the fraction form. Here 92 can be written as 92/1
So 92 – 7/15 = 92/1 – 7/15
You can not add or subtract two or more fractions till their denominators are same.
Denominators can be made same by taking LCM of denominators.
Here 1 and 15 are in denominator. LCM of 1 and 15 = 1 × 15 = 15
so to make denominator 15 in the fraction 92/1 multiply by 15 to both numerator and denominator, so that value of fraction 92 / 1 will not change.
so, 92/1 – 7/15 = (92 × 15)/(1 × 15) – 7/15
= 1380 / 15 – 7 / 15
Now subtract the numerators (1380 – 7) = 1373
= 1380 / 15 – 7 / 15 = 1373 / 15
To make this as mixed number divide 1373 by 15, quotient is 91 and remainder is 8
so answer is 91integer 8/15.

Answer 2

Two key rules to remember:

1. Any number divided by itself = 1. So, 15/15 = 1.

2. Any number multiplied by 1 = itself. So, 92*1 = 92.

So, you can take 92 * (15/15). This is still equal to 92, so you're not changing the value of the number. But, you are getting a common denominator (aka similar fraction) to the other number in your problem (7/15).

So, 92 * (15/15) = 1380/15. 1380/15 - 7/15 = 1373/15. Now, you can simplify/reduce the fraction to its lowest term.

Answer 3

Borrow 1 from the 92 and make it a fraction. So, 92 is the same as 91 and 15/15.
Now subtract your fractions and whole numbers seperately.
15/15 - 7/15 = 8/15
91 - 0 = 91
Your answer is 91 & 8/15

Answer 4

which class r u in ?! (u shud be knowin this ! )

turn the whole no. to a fraction no.
ex: 16 is a whole no. when it is a fraction, it will be 16/1
now subtract whatever u want to .

ur ques. was : 92-7/15
= 92/1 - 7/15
= (92x15) - (1x7) / (1x15)
= 1380 - 7 / 15
= 1373/15

thats it , simple !

Answer 5

92 = 92/1

=92*15 / 1*15 -Multiply both upper and lower part by 15

=1380/15
thus 92 = 1380/15

now 92-7/15

=(1380/15)-(7/15)

now as bases are equal we can say,

(1380/15)-(7/15)

=(1380-7)/15

=1373/15.

Answer 6

put them over the same denominator (in this case 15):

92 = (92*15) /15

so, 92 - 7/15 = (92*15)/15 - 7/15 = (92*15 -7) /15 = 1373/15

Answer 7

example 22-7=15

Answer 8

first , 92/1=? , 92/1=92 , understood??
therefore just use it as 92/1-7/15.
L.C.M. of 1 & 15=15
therefore,92*15=1380
1380-7=1373
the answer is 1373/15 which is 91.533333333.
Now understood it??I think you have got it right.All this comes with practice.So don't hate maths. :)

Answer 9

which class are u in dude?
anyway, just take the LCM!

92- 7/15
= 92X15/15 -7/15
= 1380/15-7/15
= 1373/15

easy!

Answer 10

92 = 91+15/15. (91+15/15) - 7/15 = 91+8/15.
