a bag contains 60 marbles, some blue and some green. the ratio of blue marbles to green ones is 1:5. how many blue marbles are t

olga55 [171]

Hello!

For every 1 blue marble there are 5 greens

You add the numbers in the ratio

1 + 5 = 6

Divide this number from the amount of marbles

60 / 6 = 10

Multiply the ratio by this

1 * 10 = 10

5 * 10 = 50

There are 10 blue marbles and 50 green ones

The answer is 10

Hope this helps!

Answer:

1 $\frac{7}{20}$

Step-by-step explanation:

1. Convert the mixed number to an improper fraction to match the rest of the problem (this just makes it easier for now, the answer will still be a mixed number)

-1 $\frac{4}{5}$ becomes $\frac{9}{5}$

2. Re-write the new equation. When there is a "+" in front of a set of parentheses the expression doesn't change aside from removing the plus signs.

The new equation becomes

$\frac{9}{5} - \frac{1}{4} -\frac{1}{5}$

3. Calculate. Just work out the new expression.

The answer is $\frac{27}{20}$

4. Convert to a simplified mixed decimal.

27 goes into 20 once with seven left over, making the answer 1 $\frac{7}{20}$
