Multiply the fraction 9/15 by the fraction 30/72 and reduce your answer to the lowest terms.?

Answer 1

Multiply across then reduce.

9 x 30 = 270

15/72 = 1080

270/1080 = 1/4

(1080/240 = 4)

Answer 2

9 (from the first fraction) cancels with 72 (from the second fraction) leaving a 1 where the 9 was and an 8 where the 72 was.
15 (from the first fraction) cancels with 30 (from the second fraction) leaving a 1 where the 15 was and a 2 where the 30 was.
You now have, after all the cancellations, 1/1 times 2/8. Multiply numerator with numerator and denominator with denominator; you get 2/8. 2/8 reduces to 1/4.

Answer 3

9/15 x 30/72
->simplify the fraction
=3/5 x 5/12
cross out the 5 on both of the fractions
=3/12
=1/4

Answer 4

your lowest term would be 1/4.9 over 15x 30 over 72, nine goes into 72 eight times, 15 goes into 30 2 times, leaving a fraction of 2 over 8, two goes into 8 4 times. answer, 1/4

Answer 5

Multiply the numerators together ad the denominators together.

9/15 * 30/72= 270/1080

divide both by 2 as many time as you can;

270/1080 = 135/ 540

We now divide the numerator and the denominator by 3 as many times as we can.
135/540 = 45 /180 = 15/ 60 =5/20

We now divide by 5. We wont be able to divide any more because we would be getting numbers in or numerator or denominator that were not integers.

5/20= 1/4
135/540

Answer 6

(9/15)(30/72) = 9(30)/[15(72)]

Note that 30/15 = 2 and 9/72 = 1/8

2/8 = 1/4

Answer 7

9/15*(30/72)=2/8=1/4. ANS.

Answer 8

3/5 x 5/12 = 3 / 12 = 1 / 4

Answer 9

9*30 / 15*72

9/72=1/8
30/15=2

2/8=1/4

Answer 10

why not reduce first ...

9/15 = (3*3) / (3*5) = 3/5
30 / 72 = (6*5) / ( 6*12) = 5/ 12

3/5 * 5/12 = 3/ 12 = 1/4
