Exercise 26 Page 208

Use the Multiplication Property of Equality to eliminate the division.

d = 5.76, see solution.

Practice makes perfect
Notice that in the given equation d is only present within the numerator of a single fraction. 9/10 = d/6.4 Let's use the Multiplication Property of Equality and multiply multiply both sides of the equation by 6.4. This will eliminate the denominator of the fraction and isolate d.
9/10 = d/6.4
MultEqn

LHS * 6.4=RHS* 6.4

6.4 * 9/10 = 6.4 * d/6.4
DenomMultFracToNumber

6.4 * a/6.4= a

6.4 * 9/10 = d
MoveLeftFacToNum

a*b/c= a* b/c

6.4 *9/10 = d
