Answer:
Estimated answer = 57.0
Exact answer = 54.04
Step-by-step explanation:
Since 19.3 is lesser than 19.5, it will be rounded down to 19.0
Since 2.8 is greater than 2.5, it will be rounded up to 3.0
<u>Estimated multiplication</u>
19.0 * 3.0 = 57.0
<u>Actual multiplication</u>
19.3 * 2.8 = 54.04
bearing in mind that 4¾ is simply 4.75.

well, the interest for each is simply A - P
695.575 - 600 = 95.575.
862.032 - 750 = 112.032.
Yes.
8 + 1 + 1 = 10, so there are 10 parts to the ratio.
3.5 litres divided by 10 would mean that each part of the ratio is worth 0.35 litres.
The colour is worth 8 parts of the ratio. 0.35 litres multiplied by 8 would give 2.8 litres, meaning 2.8 litres of colour are required.
Fiona has 2.9 litres of colour, which is more than enough to make 3.5 litres of paint mix.
