Answer:
a) they are in proportion b) they are not in proportion
Step-by-step explanation:
As it has been mentioned here that we need to identify whether the following given are in the proportion which means are they having the same ratio or not. For this, we find the ratio of both of the given fractions and then compare it.
a) 32m : 64 m = 7 sec : 14 sec
= 1 : 2 = 1 : 2
Therefore since their ratios are the same therefore they are in proportion.
b) 6.5 L : 13 L = 50 kg : 10 kg
=1 :2 = 5 :1
Since their ratios are not the same therefore they are not in proportion.
