Can you help me with this question please

Answer 1

516

Explanation:

First

34% small and 40% large means that 100 - (34 + 40) = 26% medium

26% of 600 = 0.26 × 600 = 156

----------------------------------------------------

Second

`(3)/(10)` are small and
`(1)/(10)` are large, which means
`(6)/(10)` are medium

`(6)/(10)` × 400 = 0.6 × 400 = 240

-----------------------------------------------------

Third

sum the parts of the ratio, 3 + 4 = 7

Divide 210 by 7 to find the value of one part of the ratio

210 ÷ 7 = 30 ← value of 1 part of ratio

Thus medium = 4 × 30 = 120

Total number of medium packets = 156 + 240 + 120 = 516
