how to multiply 5/4 X 3/15?

Answer 1

(5/4) x (3/15)

First: combine the numerators & denominators.

(5*3)/(4*15)
15/60

SEc: simplify the fraction into lowest terms, if possible. find a number that is divisible by the numerator & denominator, which is...15

(15/15)/(60/15)
= 1/4

Answer 2

To multiply fractions:

You multiply numerators then multiply the denominators.

numerators:
5 x 3 = 15

denominators:
4 x 15 = 60

then you get the fraction:
15/60

simplifying it by dividing it with the greatest common factor.
the common factors are 15, 5, 3 and 1
since 15 and 60 are divisible by 15, 5, 3 and 1.
we use 15 because it is the greatest of all the factors.
15 / 15 = 1
60 / 15 = 4

then you get:
1/4

another way is simplifying first then multiply.
We simplify by getting a common factor of both numerator and denominator.
With 5/4 and 3/15
We see that 5 is a factor of 5 (numerator) and 15(denominator)
then divide
5 / 5 = 1
15 / 5 = 3
then you get the fractions 1/4 and 3/3

then continue to find common factors until the common factor is only 1

since 3 is a factor of 3(numerator) and 3(denominator)
we then divide it
3 / 3 = 1
3 / 3 = 1
then we get the fractions 1/4 and 1/1

since the only common factor is 1.
we then multiply the numerators and the denominators.

numerators:
1 x 1 = 1

denominators:
4 x 1 = 4

then we get the same answer 1/4

Answer 3

Multiply the top numbers 5 and 3 to get 15 and the bottom numbers 4 and 15 to get 60. So now you have 15/60. Simplify by dividing both the top and bottom by 5 and you get 3/12 and then again by 3 for 1\4. Or divide the original answer of 15/60 by 15 to get 1/4. The same answer. You must be right!!

Answer 4

1. Multiply the numerators (the top numbers)
5 x 3 = 15

2. Multiply the denominators (the bottom numbers)
4 * 15 = 60

3. Simplify the fraction
15/60 = 1/4

Answer 5

5 x 3 = 15; 4 x 15 = 60
answer = 15/60 = 5/20 = 1/4

Answer 6

multiply the tops (5*3) = 15
multiply the bottoms (4*15) = 60

15/60 reduces to 1/4

Answer 7

3/15=1/5=4/20
5/4=25/20
25/20 X 4/20=100/400=1/4

Answer 8

first, right the problem out so that it's up and down. Next, cancel out 5 and 15. cancelling out is when u make the number smaller, so 5 and 15 would cancel out to be 1 and 3. next, multiply across and ur answer should be 3/12 and u can convert that to 1/4/

Answer 9

multiple 5 and 3 = 15
mutiply 4 and 15 = 60

15/60 or 1/4

Answer 10

5/4 X 3/15
= 5X3 and 4X15
= 15 and 60
= 15/60 simplify by 4
= 1/4
