t = 12(3/1.5) = 12(2) = 24

It will take Mark 24 minutes to make a 12-inch bracelet.

WHAT IS THE ANSWER FOR 12 1/3 + 8 3/4 +17 2/8 +23 2/3=

gulaghasi [49]

$12 \dfrac{1}{3} + 8 \dfrac{3}{4} +17 \dfrac{2}{8} +23 \dfrac{2}{3}$

Simplify
$= 12 \dfrac{1}{3} + 8 \dfrac{3}{4} +17 \dfrac{1}{4} +23 \dfrac{2}{3}$

Change the denominators to be the same
$= 12 \dfrac{1 \times 4}{3 \times 4} + 8 \dfrac{3 \times 3}{4 \times 3} +17 \dfrac{1 \times 3 }{4 \times 3} +23 \dfrac{2 \times 4}{3 \times 4}$

$= 12 \dfrac{4}{12} + 8 \dfrac{9}{12} +17 \dfrac{3 }{12} +23 \dfrac{8}{12}$

Combine into single fraction
$= 60 \dfrac{24}{12}$

$= 62$
