When multiplying fractions you just multiply the numerators together:
3X5 = 15

Then you multiply the denominators together:
10X12 = 120

So 15/120.   Now simplify
Divide both by 15
1/8

I chose 15 because I knew that off the top of my head.  If you didn't know that start with what you do know. For example

15/120 - you can divide by 5
3/24 - you can divide by 3
1/8
You still get the same answer.  If you notice dividing by 5 and then by 3 is the same as dividing by 15

Adrienne operates the milkshake machine at Burgers and Shakes. on Monday she added whipped cream to 210 shakes.This was 70% of t
Natalka [10]

Answer:

Total number of milkshakes sold on Monday = 300

Number of milkshakes without whipped cream = 90

Step-by-step explanation:

Given:

Adrienne adds whipped cream to 210 milk shakes which is 70% of the total milk shakes sold.

To find the total milkshakes sold.

Solution:

Let the total number of milkshakes sold on Monday be = x

Percentage of milkshakes with whipped cream added to them = 70%

Number of milk shakes with added whipped cream can be given as:

⇒ 70\% \textrm{ of the total number of milkshakes}

⇒ 70\% x

⇒ \frac{70}{100}x  [Representing percent in fraction form]

⇒ 0.7x  [evaluating in decimals]

We know that the number of milkshakes with whipped cream added to them = 210.

So, we have:

0.7x=210

Solving for x

Dividing both sides by  0.7

\frac{0.7x}{0.7}=\frac{210}{0.7}

∴ x=300

Thus, total number of milkshakes sold on Monday = 300

Number of milkshakes without whipped cream = 300-210= 90

Out of 300 animals in the zoo 45 are birds what percent are not birds
Leya [2.2K]

Answer:

85%

Step-by-step explanation:

There are two ways to solve this.

1. You can find the percent of birds, and then subtract that from 100%.

To find the percent of birds, divide 45/300 or make the denominator 100 by dividing both parts by 3.

45/300 (as a fraction)

=15/100

That is the same as 15%.

Subtract that from 100% and you get 85%.

2. You find the number of non-bird animals and make that a percent.

300-45=255 non-bird animals

255/300 (as a fraction)

=85/100

That is the same as 85%.

So either way, the answer is 85%.
