Answer:Holly drank 12 bottles in a week.
Step-by-step explanation:
First change the fraction 1 2/5 litre into a decimal, by doing this, we can know how many litres are there in 2/5.
So= 1 2/5
= 2 ÷5 = 0.4
= 1 + 0.4 = 1.4 liters
1.4 liters is the amount of water in a bottle.
Next, also change the fraction 2 2/5 litres into a decimal.
So=2 2/5
= 2÷5 = 0.4
= 2 + 0.4 = 2.4 liters
She drinks 2.4 liters a day.
To find how many bottles she drank in 1 week, we must multiply the amount of water she drinks in a day to the days in a week.
So= 1 week= 7 days
= 1 day= 2.4 liters
So= 2.4 × 7 = 16.8
She drinks 16.8 in a week.
To find how much bottles she drank in a week, we must divide the amount of liters she drank in one week to the amount of liters are there in a bottle.
So= 16.8 ÷ 1.4= 12 bottles
Holly drinks 12 bottles in a week.
I hope this helps! I'm sorry if it's wrong and complicated.
Lets say our number is 237x8
2+3+7+8+x should be divisible by 6.
20+x should be divisible by 6.
x=4
If he drains 1/8 of a gallon in 1/2, the amount he will drain in one hour is twice as much as 1/8.
Mateo will drain 2/8 (simplified: 1/4) of a gallon in one hour.
For Phone - 600 x 0.1 = $60
For Internet = 600 x 0.25 = $150
For Utilities = 600 x 0.6 = $360
360 + 150 + 60 = $570
600 - 570 = $30
Answer: $30
