Atoy factory can produce 135 toys in 5 hrs. at this rate how many hrs will it take to produce 243 toys.

9 hours

Step-by-step explanation:

We can use a proportion to solve this problem.  Put toys over hours

135 toys         243 toys

=

5 hours             x hours

Using cross products

135*x = 5 * 243

135x = 1215

Divide by 135 on each side

135x/ = 1215/135

x = 9 hours

a. 3/4 ÷ 1/8 = 6

step-by-step explanation:

in the question, the number line represents 3/4 divided into 6 equal units. each arrow represents a unit and there are a total of six arrows.

the size of each unit is 1/8 as shown.

showing that 1/8 divides 3/4 into 6 divisions:

3/4 ÷ 1/8

= 3/4 x 8/1

= 3/1 x 8/4

= 3 x 2

= 6

hence, the number line represents six divisions given by 3/4 ÷ 1/8.
