Using the Property a B = a K B K , Fill in the Blanks Substituting Proper Numbers in the Following. - Algebra

Sum

Using the property a/b = (ak)/(bk) , fill in the blanks substituting proper numbers in the following.
5/7 = (.......)/28 = 35/(.......) = (.........)/3.5

Solution

28 = 7 × 4, 35 = 5 × 4, 3.5 = 7 × 0.5
Now,
5/7 = (5 xx 4)/(7 xx 4) = (5 xx 7)/ (7 xx 7) = (5 xx 0.5)/( 7 xx 0.5)

⇒ 5/7 = (20)/( 28) = (35)/(49)= ( 2.5)/ (3.5)
