Question

Toppr Admin · Accepted Answer

-4 - 7- and -16 - 21-Given fractions are -4 - 7- and -16 - 21-By cross multiplication we get-4 -times 21- - 84-7 -times 16- - 112-Now -4 -times 21- -neq -7 -times 16-Hence- -4 - 7- and -16 - 21- are not the pairs of equivalent fractions-

Check if the following is a pair of equivalent fractions?

$$4/7$$ and $$16/21$$

$$4 / 7$$ and $$16 / 21$$
Given fractions are $$4 / 7$$ and $$16 / 21$$
By cross multiplication we get
$$(4 \times 21) = 84$$
$$(7 \times 16) = 112$$
Now $$(4 \times 21) \neq (7 \times 16)$$
Hence, $$4 / 7$$ and $$16 / 21$$ are not the pairs of equivalent fractions.

Check if the following is a pair of equivalent fractions?$$4/7$$ and $$16/21$$

$$4 / 7$$ and $$16 / 21$$Given fractions are $$4 / 7$$ and $$16 / 21$$By cross multiplication we get$$(4 \times 21) = 84$$$$(7 \times 16) = 112$$Now $$(4 \times 21) \neq (7 \times 16)$$Hence, $$4 / 7$$ and $$16 / 21$$ are not the pairs of equivalent fractions.
