RUDIKE [14]

Answer:

3.728 cm²

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)

aleena has a watering can. she uses 3/8 gallonto water her roses and1/3 gallon to water the geraniums . How much water did. Alee

WINSTONCH [101]

The answer is simple to work out you do 3/8 + 1/3

but the denominators are different so you find the lowest common multiple in this case 24 .
the frection is now 9/24 + 8/24 this is 17/24
I changed the fraction by doing this 24(common multiple) divided by 8 (denominator) that's how I got it if you don't understand just ask me
