Question

1⁄5 × 4⁄7 × 3⁄4=? I will give brainliest if you are correct

Answer 1

Answer:

$\frac{3}{35}$

• Start with 1/5 × 4/7

$\frac{1}{5} *\frac{4}{7} = \frac{1 * 4}{5 * 7} = \frac{4}{35}$

• Preserve $\frac{4}{35}$ as x, it will be of good use in just a moment.

$\frac{4}{35} = x$

• Multiply x($\frac{4}{35}$) by $\frac{3}{4}$

$x * \frac{3}{4}$

• To do this, you have to substitute the numerator(4) as x, and the denominator(35) as y.

$\frac{x(4) * 3}{y(35) * 4} = \frac{12}{140}$

• Simplify using the LCD Least Common Denominator.

$\frac{12 / 4}{140 / 4} = \frac{3}{35}$
