Answer:

Step-by-step explanation:
In this question, one is asked to multiply a fraction by a whole number, first model the question.

In a situation like this, one multiplies the whole number by the numerator (number) over the fraction.

Simplify,

A common error that people make is that they will multiply both the numerator and denominator by the whole number, this is the same as multiplying the answer by (1), thus it is incorrect.
54÷2 since there 2 girls for each boy so 2 girls for 1 boy and there 54 girls

Answer:
The diameter is 12
Step-by-step explanation:
37.68/3.14 = D π/ 3.14
D = 12 The diameter equals twelve.
We can represent this situation by the equation 2x+4x+5x=33.
Then 11x=33, and x = 3.
Then the children's ages are in the ratio 2x:4x:5x, or 2(3):4(3):5(3), or
6:12:15.
Do these 3 ages add up to 33? 6 + 12 + 15 = 33? YES!
The children's ages are 6, 12 and 15 years respectively.
Answer:
22
Step-by-step explanation:
3x = x+44(base angle of isosceles triangle are equal)
2x = 44
x = 22
