Chapter 4: Q59. (page 181)

Use cross products to solve each proportion.

x8=34

Short Answer

Expert verified

Given proportion is simplified to x=6

Step by step solution

01

- Cross product between two proportions

Let ab and cd be two equal proportions that is ab=cd

Then cross product is defined as multiplication of denominator of one proportion with the numerator of other proportion, that is ad=bc

02

- Substitution

Substitute x for a, 8 for b, 3 for c, and 4 for d into ad=bc gives

x脳4=8脳3

03

- Simplify x×4=8×3

To simplify this expression multiply both the numbers of right side and then divide it from number on the left as shown below.

4x=24x=244x=6
