Show two ways to multiply 2/15 x 3/20. Then tell wich way is easier and justify your choice
Radda [10]

The easier way to multiply 2/15 by 3/20 will simply be by multiplying the numerators and denominators.

In order to multiply 2/15 x 3/20, we can simply multiply the numerator and the denominator. This will be

= 2/15 × 3/20

= 6/300

= 1/50

Also, in order to multiply the fractions, we can change them to decimal first. This will be:

= 2/15 × 3/20

= 0.133 × 0.15

= 0.01995

In conclusion, multiplying the numerators and denominators is easier and faster.

10. Mr. Hanson is preparing an activity for his
Anna71 [15]

Answer:

H

Step-by-step explanation:

Out of all of the answers provided, H seems like the equation that makes the most sense.

(60 * 3) = 180

[480 - (180)] = 300

300 = 60

Make sure you divide 300 sticks by 60 sticks (box max) to get the number of boxes.

300 / 60 = 5

So, Mr. Hanson would need to have 5 more boxes in order to get the total amount of 480 sticks.

From that, H would be considered the best equation that Mr. Hanson would use.
