Step-by-step explanation:
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
The volume of the rectangular prism is 20.7 inches
I don’t know how to do that
Answer:
2/3
Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points, then simplify:
(y2 - y1) / (x2 - x1)
(-1 + 7) / (4 + 5)
6/9
= 2/3
So, the slope of the line is 2/3
Answer:
98
Step-by-step explanation:
9(12 + 5) - 11(21 - 8 x 2)
(108 + 45) - 11(21 - 16)
153 - (231 - 176)
153 - 55 = 98
