Answer:
1/2 or .5 or 1:2
Step-by-step explanation:
Answer:
<u>390.4 in.²</u>
Step-by-step explanation:
- Area of sector = πr² x θ/360
- Area = 22/7 x 64 x 70/360
- Area = 11 x 10 x 32 x 1/9
- Area = 320 x 11/9
- Area = 320 x 1.22
- Area = <u>390.4 in.²</u>
In order to multiply or divide a fraction by a mixed numeral, it is best to have them BOTH in fraction form. 1) We'll convert 1 2/5 into an improper fraction. (1×5)+2 = 7/5
Now 6/7 ÷ 7/5
2) when dividing by a fraction, it is the same to multiply by its reciprocal. So flip the second fraction and multiply them: 6/7 ÷ 7/5 = 6/7 × 5/7
3) reduce them: there is nothing on top that reduces with the bottom, so we simply multiply
4) multiply numerators, then multiply denominators and keep them in place: 6×5 = 30, 7×7 = 49
5) so our final answer is 30/49
