Answer:
His sister sent 6 more messages than Diego.
Step-by-step explanation:
Ratio of Diego's messages to his sister's messages = 3 : 4
Text messages sent by Diego = 18
Text messages sent by his sister = x
Ratio = 18 : x
It is a proportional relationship,
3 : 4 :: 18 : x
Product of extremes = Product of means
3x = 18*4
3x = 72
Difference = 24 - 18 = 6
Therefore,
His sister sent 6 more messages than Diego.

Answer:
Step-by-step explanation:
Evan spent 20 hours doing homework last week
25 hours were spent this week.
<u>Let's see what 125% of 20 equals:</u>
= (125 / 100) * 20
= (125 / 10) * 2
= 125 / 5
= 25 hours
But,
<u>It is written that Evan thought he spent 125 % more than the last week which means:</u>
= (125% of 20) + 20
= 25 + 20
= 45 hours
He should've said that he has given 25% more time than the last week.
(<u>Note that:</u> 25 % of 20 equals 5 so 25 % more than last week will be equal to (25 % + 20) = (5+20) = 25)
Hope this helped!
