4/5 ÷ 7/30 please hellllpppp

Softa [21]

Answer:

$\frac{24}{7}$ or $3\frac{3}{7}$

Step-by-step explanation:

$\frac{4}{5}\div \frac{7}{30}$

Step 1: Apply the fraction rule: $\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}$

$=\frac{4}{5}\times \frac{30}{7}$

Step 2: Cross-cancel common factor: 5

$=\frac{4}{1}\times \frac{6}{7}$

Step 3: Multiply fractions: $\frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}$

$=\frac{4\times \:6}{1\times \:7}$

Step 4: Multiply the numbers: $4\times \:6=24$

$=\frac{24}{1\times \:7}$

Step 5: Multiply the numbers: $1\times \:7=7$

$=\frac{24}{7}$

Therefore, the answer is $\frac{24}{7}$ or in the simplified form; $3\frac{3}{7}$
