Question

3 9/10 - (2 - 1 11/35) : 9/49 + 1/2​

Answer 1

$3\frac{9}{10} - (2-1\frac{11}{35} ):\frac{9}{49} +\frac{1}{2} =$$\frac{2}{3}$

$2-1\frac{11}{35} =\frac{70-46}{35} =\frac{24}{35}$

$2) \frac{24}{35} : \frac{9}{49} = \frac{56*21}{15*21} =\frac{56}{15} =3\frac{11}{15}$

$3)3\frac{9}{10} -3\frac{11}{15} =\frac{1}{6}$

$4)\frac{1}{6} +\frac{1}{2} =\frac{2}{3}$
