I NEED HELP SOLVING THIS PROBLEM ,PLEASE EXPLAIN AND SHOW HOW TO SOLVE the answer ."I HAVE 63 LITERS OF HYDROGEN PEROXIDE, HOW MANY TEST TUBES CAN I FILL IF EACH CONTAINED 7/8 OF A LITER?" PLEASE SHOW ME YOUR WORK. AND THANK YOU IN ADVANCED.
numbertesttubes*volumetesttueb=totalvolume
number= 63liter/(7/8 liter)= 63*8/7 test tubes.
5x-7=33
To solve this problem, we need to divide the total amount of hydrogen peroxide by the amount in each test tube.
First, let's convert the 7/8 of a liter to a decimal. We do this by dividing the numerator (7) by the denominator (8):
7 ÷ 8 = 0.875
Now, we can divide the total amount of hydrogen peroxide (63 liters) by the amount in each test tube (0.875 liters):
63 ÷ 0.875 = 72
Therefore, you can fill 72 test tubes with 7/8 liters of hydrogen peroxide each.
Here's the breakdown of the calculation:
1. Convert 7/8 to a decimal: 7 ÷ 8 = 0.875
2. Divide the total amount of hydrogen peroxide by the amount in each test tube: 63 ÷ 0.875 = 72
Therefore, you can fill 72 test tubes with 7/8 liters of hydrogen peroxide each.
