Question

Answer 1

Liters of vinegar is 0.525 liters or 21/40

Explanation:

Container holds 0.7 liters

We are looking for the liters of vinegar

We use cross-multiplication

a/b=c/d

?/3/4= 0,7/1

?=0,7 x (3/4) /1

?= 0.525 liters

To get the fraction

we use the fraction in liters that is 7/10

7/10 x 3/4

For fraction multiplication, multiply the numerators and then multiply the denominators to get

7×3/10×4=21/40

This fraction cannot be reduced.
