You have to divide the number by the denominator of the fraction. For example, if you want to find 1/5 of 20, you have to divide 20 by 5 and that tells you that 1/5 of 20 is 4.

Mingfa says, "My sister and I have $130 altogether. If my mother gives me another
quester [9]

Given:

Total amount of Mingfa and her sister = $130

If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.

To find:

How much money does Mingfa actually have?​

Solution:

Let, Mingfa have $x and her sister has $y initially. Then,

x+y=130                ...(i)

If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.

x+10=3y              ...(ii)

Substitute the value of x from (ii) in (i).

(3y-10)+y=130

4y=130+10

4y=140

Divide both sides by 4.

y=35

Putting y=35 in (i), we get

x+35=130

x=130-35

x=95

Therefore, Mingfa have $95.

RUDIKE [14]

Answer:

3.728 cm²

90

Step-by-step explanation:

To built the envelope I am using a rectangular piece of material 28 m long and 12 m wide.  

Out of this material, I have to cut patches that are 1/12 the length and 2/15 the width of the whole material.

So, the length of the patches is 28 \times \frac{1}{12} = 2.33 m and the width of the patches is 12 \times \frac{2}{15} = 1.6 m.

Therefore, the area of the patches is (1.6 × 2.33) = 3.728 m² each. (Answer)

Now, the area of the rectangular piece of material is (28 × 12) = 336 m²

Hence, \frac{336}{3.728} = 90.37 ≈ 90 such patches can be made out of the whole material. (Answer)
