Question

Are 17 : 51 and 170 : 510 in proportion? Write the middle and extreme terms.

Answer 1

Answer:

Yes, 17 : 51 and 170 : 510 are in proportion

Tricks

17x510 = 51x170

We know, the first term (1st) and the fourth term (4th) of a proportion are called extreme terms or extremes, and the second term (2nd) and the third term (3rd) are called middle terms or means. Therefore, in a proportion, product of extremes = product of middle terms.
