Question

the formula for glue says to add 60 ml of hardener to each container of resin. How much hardener should be added to 19 containers of resin?

Answer 1

19x60=1140
19 containers of resin with 60 ml of hardener each so the total is 1140 ml of hardener.

Answer 2

Find out the how much hardener should be added to 19 containers of resin .

To prove

Let us assume that the hardener should be added to 19 containers of resin be x .

As given

The formula for glue says to add 60 ml of hardener to each container of resin.

than the equation become

x = 19 × 60

x = 1140 ml

Therefore the 1140 ml hardener should be added to 19 containers of resin .

Hence proved
