Question

In a box the ratio of nails to screws is 4:7. If there are 40 nails how many screws are there? *

Answer 1

Answer:

Let nails = x and screw = y

x/y= 4/7 is given

also it is given that x= 40

so y = (7/4)x

y= (7/4)×40

y= 70

Answer 2

Answer:

25 approximately

Step-by-step explanation:

Taking common multiple as x

so, 4x+7x=40

11x=40

x=40/11

x=3.6

No. of nails =4x=4×3.6= 14.4

No. of screws=7x=7×3.6=25.2
