Answer 1

OK so we have \(\dfrac{240}{25}=\dfrac{x}{45}\) we have to solve for X... Do you know how?

Answer 2

Wait, would the minutes be the numerator or denominator? Sorry I am confusing myself now o-o

Answer 3

Idk..

Answer 4

OK, anyways. Let's start solving for x

Answer 5

We first cross multiply 240 by 45, so what is 240*45?

Answer 6

10800

Answer 7

@sammixboo

Answer 8

may i help?

Answer 9

Please do.

Answer 10

the machine produces 240 bolts in 25 minutes

Answer 11

so it will produce 240/25 bolts in 1 minute

Answer 12

9.6?

Answer 13

no. of bolts produced in 45 minutes = no. of bolts produced in 1 minute * 45 (which is minutes)

Answer 14

no. of bolts produced in 45 minutes = 45* 240/25 = 9.6*45 = ??

Answer 15

so would 432 be the answer

Answer 16

Answer 17
