Isabelle ordered 3 flower arrangements to send to her sisters. Each arrangement, weighs 6 2/3 pounds. What was the total weight
Liono4ka [1.6K]

Answer: 20 pounds.

Step-by-step explanation:

We know the weight of each flower arrangement (each one weighs 6 2/3 pounds) and the total number of flower arrangaments Isabelle ordered (3 flower arrangements).

To make the calculus easier, we can rewrite the mixed number 6 2/3 as a decimal number:

Divide the numerator 2 by the denominator 3 and add the result to the whole number 6:

(6+0.666)lb=6.666lb

If 1 arrangement weighs 6.666 pounds, the total weigth of 3 arrangements can be calculated by multiplying 6.666 pounds by 3:

weight_{(total)}=(6.666lb)(3)\\weight_{(total)}=20lb

A 16 1/2 kilometer stretch of road needs repairs. Workers can repair 2 1/4 kilometer of road per week. How many weeks will take
liraira [26]

Answer:

7\frac{1}{3}\ weeks

Step-by-step explanation:

we know that

To find out how many weeks it will take to repair this stretch of road, divide the total length of the road by the workers' rate

so

\frac{16\frac{1}{2}}{2\frac{1}{4}}

Convert mixed number to an improper fraction

16\frac{1}{2}\ km=\frac{16*2+1}{2}=\frac{33}{2}\ km

2\frac{1}{4}\ km=\frac{2*4+1}{4}=\frac{9}{4}\ km/week

substitute

(33/2)/(9/4)=\frac{132}{18}\ weeks

Convert to mixed number

\frac{132}{18}\ weeks=\frac{126}{18}+\frac{6}{18}=7\frac{1}{3}\ weeks
