Sam has 13 1/2 yards of ribbon.He cuts the ribbon into pieces that measure 3/4 yard. What is the maximum number of pieces of rib
Dominik [7]

Answer:

18

Step-by-step explanation:

Number of pieces = Length of ribbon/Length of each piece

                              = (13½) ÷ (¾)

Convert the mixed number to an improper fraction

No. = (²⁷/₂) ÷ (¾)

Invert the proper fraction and change division to multiplication

No. = ²⁷/₂ × ⁴/₃

Cancel the 2s

No. = 27 × ⅔

Cancel the 3s

No. = 9 × 2

No. = 18

Sam can cut 18 pieces of ribbon.

Dayami works at Future Shop and earns $10.50/h plus 6% commission on sales. Last
skad [1K]
<h2><u>Quick answer</u> :</h2>

= \tt\$570

<h2><u>Answer with steps</u> :</h2>

Money Dayami earns for an hour's work = $10.50

Number of hours Dayami worked last week = 40

Money Dayami would have gotten for her work :

=\tt 10.50 \times 40

=\tt  \$ \: 420

Thus, money earned by Dayami for her work = $420

Total sales Dayami made last week = $2050

Money Dayami must have earned as commission :

= 6% of total sales

= \tt6 \% \: of \: 2500

=  \tt\frac{6}{100}  \times 2500

=\tt  \frac{15000}{100}

=\tt \$150

Thus, money Dayami earned as a commission = $150

Dayami's weekly gross salary last week :

= \tt420 + 150

=\color{plum} \tt \: \$570

Thus, total salary = $570

Therefore, Dayami's gross salary last week =<u> $570</u>
