Answer 1

$1 \times \frac{3}{4} \div 3.75 = 4x \div 15$
$1.75 \div 3.75 = 4x \div 15$
$\frac{7}{15} = 4x \div 15$
$\frac{7}{15} = \frac{4x}{15}$
$7 = 4x$
$x = \frac{7}{4}$
$x = 1 \times \frac{3}{4}$

$\frac{1}{2} \div 13 = \frac{1}{3}x \div 4 \times \frac{1}{3}$
$\frac{1}{26} = \frac{1}{3}x \div 4 \times \frac{1}{3}$
$\frac{1}{26} = \frac{1}{13} x$
$x = \frac{1}{2}$
