Question

Check wheather arethe number 30 .40.45.60. are in proportion or not

Answer 1

Answer:

yes they are in proportion

Step-by-step explanation:

30:40::45:60

to check we need that ratio 30:40 and 45:60

should have equal value

so cancel both ratios

30:40= 3:4. (cancel by 10)

and

45:60 = 3:4. (cancel by 15)

both ratios have equal value so we can say

30:40::45:60

or

they are in proportion.
