There should be two characteristics that we look at the numbers when grouping them.
The first one is their signal, if they are positive, or negative.
The second one is if they are decimal, or not.
Looking at these characteristics, we can see the sets in which they belong.
We only know the first number to three significant figures so we can approximate the rest as 10 and call the sum 2620.

Answer:
No. He had not made cherry pink paint
Step-by-step explanation:
Rose Pink red : white = 1 : 2
Cherry Pink red : white = 4 : 3
<em>...he adds 80 litres of red paint and 28 litres of white paint.</em>
The question basically want us to check if it follows the ratio.
To have the cherry pink, the ratio must be 4:3 however the ration of paint he mixed is;
80 : 28 which is equivalent to 20 : 7
This means he had not made cherry pink paint
Answer:
It is three times as large
Step-by-step explanation:
If a ration is also a fraction, and your wording is correct than an enlargement of 1:3 where 1 is the original shape would suggest that the 3 would be that same original shape, be enlarged in terms of 3 compares to 1 so a 300% enlargement.
if the original rectangle has a 16 cm perimeter, than the new rectangle has a 48 cm perimeter.
