Question

Answer 1

\(\dfrac{1}{3}\times16\times\dfrac{3}{8}=2\)

\(\dfrac{22}{5}-\left(\dfrac{15}{35}+\dfrac{49}{35}\right)=\dfrac{22}{5}-\dfrac{64}{35}=\dfrac{154}{35}-\dfrac{64}{35}=\dfrac{90}{35}=\dfrac{18}{7}\)

Answer 2

a) 1/3 x 16 : 8/3

= 1/3 : 8/3 x 16

= 1/3 x 3/8 x 16 

= 1/8 x 16 = 2

b) 22/5 - (3/7 + 7/5)

= 22/5 - 3/7 - 7/5

= 22/5 - 7/5 - 3/7

= 3 - 3/7 = 18/7

Answer 3

225−(1535+4935)=225−6435=15435−6435=9035=187
