Toys produced in 4 sec= 8
...........................1 sec= $$\frac{8}{4}$$
...........................120 sec= $$\frac{8}{4}$$*120= 240

Machine's rate in seconds:$$\frac{8toys}{4secs}$$

Denominator of 4 divides evenly into 60 seconds (4*15 = 60). Multiply numerator by 15, too. Rewrite rate as "per minute."

$$\frac{8toys}{4secs}=\frac{(8*15)toys}{(4*15)mins}=\frac{120toys}{60secs}=\frac{120toys}{1min}$$

How many toys in 2 minutes?
$$\frac{120toys}{1min} * 2 mins = 240$$ toys

The rate of the machine is 8/4 = 2 toys per second.

Since 2 minutes = 120 seconds the machine can produce 2 x 120 = 240 toys in 2 minutes.

If you notice quickly 4 * 15 =60, it will help quickly to solve.

8 toys in 4 seconds ...multiply by 15

15*8 toys in 60 seconds (1 minute).........Do not waste time to get 15 * 8

To get what produced in 2 minutes, just multiply the above by 2.

2*15*8 toys in 120 seconds...Now easy to multiple 2*15*8 =30 * 8 =240
