Problem #3: Jamie is decorating 45 cookies for her pirthday party. She decorates 1/3 of the cookies with pink sprinkles. Then she decorates 2s of the remaining cookies with heart sprinkles and the rest of the cookies had blue sprinkles. How many cookies had blue sprinkles?

Respuesta :

Since she decorating 45 cookies

Since she decorates 1/3 of them with pink sprinkles

Let us find 1/3 of 45

[tex]\because\frac{1}{3}\times45=15[/tex]

Then the remaining = 45 - 15

The remaining cookies = 30

Since she decorates 2/5 of the remaining with heart sprinkles

Let us find 2/5 of 30

[tex]\frac{2}{5}\times30=12[/tex]

Then the rest = 30 - 12

The rest = 18

She decorates 18 cookies with blue sprinkles
