Answer:

168

Step-by-step explanation:

Sum the parts of the ratio, 6 + 7 = 13 parts

Divide the total number of students by 13 to find the value of one part of the ratio.

364 ÷ 13 = 28 ← value of 1 part of the ratio, thus

number of girls = 6 × 28 = 168

How are a common denominator and a common multiple alike and different?
grigory [225]
The Common Denominator is the bottom part of a fraction which has been matched to 2 or more fractions. For example 1/2 + 1/4 is easier if you use 2/4 + 1/4 = 3/4. You can also use it for 3/5 + 1 2/3 Becomes 3/5 + 5/3 (Improper fraction) and you change that to 9/15 + 25/15 = 34/15 = 2 4/15

I need help with this problem
Soloha48 [4]

Answer:

3.\ \dfrac{3x}{11x}, \dfrac{6}{22},  \dfrac{9}{33},\dfrac{12}{44}

4. -18\\5.\ 400

Step-by-step explanation:

<u>Solution 3:</u>

Equivalent fractions to are to \frac{3}{11} be found out.

<u>Method: </u> By Multiplying both the denominator and numerator with the same number, we can easily find equivalent fractions.

1. Multiply with 2:

\dfrac{3 \times 2}{11 \times 2}\\\Rightarrow \dfrac{6}{22}

2. Multiply with 3:

\dfrac{3 \times 3}{11 \times 3}\\\Rightarrow \dfrac{9}{33}

3. Multiply with 4:

\dfrac{3 \times 4}{11 \times 4}\\\Rightarrow \dfrac{12}{44}

If we try to write in variable form, it can be written as:

\dfrac{3x}{11x}

where x is any number.

---------------

<u>Solution 4:</u>

(2x-10) when x=-4

2 \times (-4) -10\\\Rightarrow -8 -10\\\Rightarrow -18

------------

<u>Solution 5:</u>

(10a)^2, a=-2\\\Rightarrow \{10 \times (-2)\}^2\\\Rightarrow (-20)^2\\\Rightarrow 400
