In each pair, tell if the fractions are equal by using cross multiplication.
a. 5/30 and 1/6
b.4/12 and 21/60
c. 17/34 and 41/82
d. 6/9 and 25/36

a. 5/30 and 1/6 ---> are equal

b.4/12 and 21/60 ---> are not equal

c. 17/34 and 41/82 ---> are equal

d. 6/9 and 25/36 ---> are not equal

Step-by-step explanation:

case a) we have  5/30 and 1/6

equate the fractions

using cross multiplication

----> is true

therefore

The fractions are equal

case b) we have  4/12 and 21/60

equate the fractions

using cross multiplication

----> is not true

therefore

The fractions are not equal

case c) we have  17/34 and 41/82

equate the fractions

using cross multiplication

----> is true

therefore

The fractions are equal

case d) we have  6/9 and 25/36

equate the fractions

using cross multiplication

----> is not true

therefore

The fractions are not equal

a. The fractions are equal.

b. The fractions are not equal

c. The fractions are equal.

d. The fractions are not equal

Step-by-step explanation:

By definition, equivalent fractions have the same value, but they look different.

In order to verify if two fractions are equivalent, you can use Cross multiplication.

The procedure is: multiply the numerator of the first fraction by the denominator of the second fraction, and the numerator of the second fraction by the denominator of the first fraction.

Then:

correct answer:

b.(19,-2)

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.
