Estimate 2/3 x 10
To estimate the area of a rectangle, you need to multiply its length by its width.
1) For the first rectangle with dimensions 5 7/9 by 3 1/5:
- Convert the mixed numbers to improper fractions:
- 5 7/9 = (5 * 9 + 7)/9 = 52/9
- 3 1/5 = (3 * 5 + 1)/5 = 16/5
- Multiply the fractions: (52/9) * (16/5) = 832/45
- To estimate the value, round the result to the nearest whole number or decimal places as desired.
2) For the second rectangle with dimensions 7 7/8 by 1 1/3:
- Convert the mixed numbers to improper fractions:
- 7 7/8 = (7 * 8 + 7)/8 = 63/8
- 1 1/3 = (1 * 3 + 1)/3 = 4/3
- Multiply the fractions: (63/8) * (4/3) = 252/24
- To estimate the value, round the result to the nearest whole number or decimal places as desired.
To estimate the product of a fraction and a whole number, you need to multiply the numerator of the fraction by the whole number.
3) For the fraction 3/8 multiplied by 4:
- Multiply the numerator of the fraction by the whole number: 3 * 4 = 12
- The estimated product is 12.
