Question

Determine whether the following ratios
form a proportion or not. If they form a
proportion, write the middle terms and
the extreme terms.
a) 0.5 kg : 0.45 kg and 110: 99
b) 6 L : 24 L and 18 km : 72 km​

Answer 1

Answer:

0.45 kg and 24 L and 18 km is the middle terms.

0.5 kg and 110: 99; 6 L : 24 L and 18 km : 72 km are extreme terms.

Answer 2

Part a is in proportion..... 0.5 and 99 are extreme terms and 0.45 and 110 are middle terms

part b is also a proportion......6l and 72km are extreme terms and 24l and 18km are middle terms ....

to know whether they are in proportion multiply the extreme terms and then multiply the mean terms ...if their product is same they are in proportion...if they are not same then they are not in proportion
