15 times as much as 1 fifth of 12
Ann [662]
1) Work out what 1/5 of 12 is
To do this, we divide 12 by 5
12/5 = 2.4

2) Multiply 2.4 by 15
2.4 x 15 = 36

<em>If you don't like decimals, you can also do it this way...
</em>
This can be rewritten as 15  x  1/5  x  12
Multiplications alone can be performed in any order

1) Work out what 1/5 of 15 is
1/5 of 15
15/5 = 3

2) 3 multiplied by 12
3 x 12 = 36

Collins Middle School has 240 sixth grade students. If the sixth grade is 30% of the total school, how many students are in the
Masteriza [31]

Answer:

800

Step-by-step explanation:

We can set up a proportion using the information we are given. We know that 240 students corresponds to 30% and that the total number of students, x, corresponds to 100%

\frac{240}{x} = \frac{30}{100}

Cross multiply and solve:

240 * 100 = 30x

24000 = 30x

800 = x

-16 + 5n= -7(-6 + 8n) + 3
Amiraneli [1.4K]

\text{Hello there!}\\\\\text{In this question, we're trying to solve the equation}\\\text{We would use the distributive property and solve after that}\\\\\text{Lets solve:}\\\\-16 + 5n= -7(-6 + 8n) + 3\\\\\text{Distribute the -7 to the numbers inside the parenthesis}\\\\-16 + 5n= 42 -56n + 3\\\\\text{Add 56n to both sides}\\\\-16 + 61n= 42  + 3\\\\\text{Add 16 to both sides}\\\\61n= 42  + 3 + 16\\\\61n= 42  + 3 + 16\\\\61n= 45 + 16\\\\61n = 61\\\\\text{Divide both sides by 61}

n = 1
