Question

How to solve if 5a=6 and 7b=8, 35ab= (please explain, i need explaination)

Answer 1

Answer:

35ab = 48

Step-by-step explanation:

given

5a = 6 ( divide both sides by 5 )

a = $\frac{6}{5}$

and

7b = 8 ( divide both sides by 7 )

b = $\frac{8}{7}$

substitute these values for a and b into the expression and simplify

35ab

= 35 × $\frac{6}{5}$ × $\frac{8}{7}$ ( divide 35 and 5 by 5 )

= 7 × 6 × $\frac{8}{7}$

= 42 × $\frac{8}{7}$ ( divide 42 and 7 by 7 )

= 6 × 8

= 48
