Question

solve = 21 / 3 × 15 / 4 × 4 / 2​

Answer 1

Answer:

105/2 = 52.5

Step-by-step explanation:

$\frac{21}{3} *\frac{15}{4} *\frac{4}{2} \\\\\frac{7}{1} *\frac{15}{1} *\frac{1}{2} \\\\\frac{105}{2} \\\\52.5$

Answer 2

$\frac{21}{3} \times \frac{15}{4} \times \frac{4}{2}$

• 21 ÷ 3 = 7
• 4 ÷ 2 = 2

$7 \times \frac{15}{4} \times 2$

• 2 ÷ 4 = 1/2

$7 \times \frac{15}{2}$

$\frac{7 \times 15}{2}$

$\frac{105}{2}$

$52.5$

52.5 is the answer
