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.
Answer:
Scale factor = 3.24
Step-by-step explanation:
162 ÷ 50 = 3.24
How many 8 can we fit in 144?
Start with 8•10=80, can’t fit another 80 so
Continue with 8•5=40 we have now 80+40=120 and we need 144 so are left 24
Finish with 8•3=24
Now we can group them
Multiplication: 8•10+8•5+8•3=144
Distributive : 8•(10+5+3)=144
So 144/8=10+5+3=18
