Question

how to check 15:5 is proportion to 10:5​

Answer 1

Step-by-step explanation:

15 : 5 : : 10 : 5?

To check that they are in proportion, we have to multiply 2 outmost number and 2 inmost number.

= 15 x 5 = 5 x 10

= 75 ≠ 50

Answer 2

Answer:

15:5: : 10:5

15 and 5 are product of extremes

5 and 10 are product of means.

now multiply both extremes and means

15 × 5 = 75

5×10= 50

thus 15:5 and 10:5 are not in proportion
