Question

whether the following group of number are in proportion (a) 25,30,40,48​

Answer 1

Step-by-step explanation:

25, 30, 40, 48 (to determine whether they are in proportion)

If a÷c=b÷d (numbers are said to be in proportion)

a÷b = 25÷ 30 = 5÷6

c÷d =40÷48 = 5÷6

since, a÷b = с÷d

(They are in proportion).
