Samantha measured inches for the entire month
Step-by-step explanation:
Samantha is measuring the snowfall in a snow Gog for her science project
- The first week she measured 3 3/4 inches of snow
- The second week she measured twice as much snow, and the third week she measured half as much snow as the first week
- It did not snow at all in the fourth week
We need to find how much snowfall Samantha measured for the entire month
∵ She measured inches of snow in the 1st week
- Change the mixed number to improper fraction
∵
∴ She measured inches of snow in the 1st week
∵ She measured twice as much snow as the 1st week in the 2nd week
- Multiply the value of the 1st week by 2
∵ × 2 =
∴ She measured inches of snow in the 2nd week
∵ She measured half as much snow as the 1st week in the 3rd week
- Multiply the value of the 1st week by 1/2
∵ ×
=
∴ She measured inches of snow in the 3rd week
∵ It did not snow at all in the fourth week
- Add the values of the three weeks above to find the amount
of snowfall she measured for the entire month
∵ The amount of snowfall =
- To add the fraction you must make all the denominator same number
so multiply the 1st and 2nd fractions by 2 up and down to make all
the denominator equal 8
∴ The amount of snowfall =
- Add the numerators and put the sum over 8
∴ The amount of snowfall =
- You can change the improper fraction to mixed number by divide
105 by 8 and put the reminder over 8
∵ 105 ÷ 8 = 13 and 1/8
∴ The amount of the snowfall = inches
