Cameron task: 3/7 × 2/9
What he did:
• Simplify 3/7 to 1/7
• mulitiplied the fractions 1/7 and 2/9
Cameron's error was:
• The "simplification":
To simplify a fraction is to reduce to the lowest possible multiple. Illustration:
Simplify 16/100
= 2/25
But in the case of 3/7, the answer is 3/7.
What Cameron would have done:
1. 3/7 = 2/7 + 1/7
3/7 × 2/9 = (2/7 × 2/9) + (1/7 × 2/9)
= 4/63 + 2/63
= 6/63
2. since he simplified 3/7 to 1/7
1/7 = 3/7 × 1/3
Therefore,
3/7 × 2/9 = 1/7 × (2/9 × 3)
= 1/7 × 6/9
= 6/63
Answer:
m = 1/10
Step-by-step explanation:
1 2/3m + 2= 2 1/6
Subtract 2 from each side
1 2/3m + 2-2= 2 1/6-2
1 2/3 m = 1/6
Change the mixed number to an improper fraction
1 2/3 = (3*1+2)/3 = 5/3
5/3m = 1/6
Multiply each side by 3/5 to isolate m
3/5 * 5/3m = 3/5*1/6
m = 3/30
Divide the top and bottom fraction on the right hand side by 3
m = 1/10

Answer:
C. 50.24 inches
Step-by-step explanation:
The area of a circle can be represented by
. To find the circumference, all we need to do is know the radius, and then we can plug that value into the circumference formula
. So, to find the radius we see that:


So, the circumference is:
, which is closest to the answer C) 50.24 inches.
Hope this helped! :)
