Answers

Answer 1

Divide 14% by 60ml
* EX. How to calculate percentage of a number. Use the percentage formula: P% * X = Y
Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.*
You get 8.4ml

Answer:

5/6

Step-by-step explanation:

1 4/6-5/6=?

1 4/6=10/6

10/6-5/6=5/6

Answer:

five sixths pound

Step-by-step explanation:

Kip bought [tex]1\frac{4}{6}[/tex] pounds of toffee. He gave [tex]\frac{5}{6}[/tex] of a pound to his friend. How much toffee does he have left?

The narrator is asking how much he has left after giving some toffee to his friend, that means we have to subtract.

[tex]1\frac{4}{6}[/tex] - [tex]\frac{5}{6}[/tex]

We already have an equal denominator so we can just subtract.

[tex]\frac{10}{6}-\frac{5}{6}[/tex] = [tex]\frac{5}{6}[/tex]

Kip has [tex]\frac{5}{6}[/tex] pounds left.
