Answer:

35ab = 48

Step-by-step explanation:

given

5a = 6 ( divide both sides by 5 )

a = [tex]\frac{6}{5}[/tex]

and

7b = 8 ( divide both sides by 7 )

b = [tex]\frac{8}{7}[/tex]

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

35ab

= 35 × [tex]\frac{6}{5}[/tex] × [tex]\frac{8}{7}[/tex] ( divide 35 and 5 by 5 )

= 7 × 6 × [tex]\frac{8}{7}[/tex]

= 42 × [tex]\frac{8}{7}[/tex] ( divide 42 and 7 by 7 )

= 6 × 8

= 48
