Ten percent of 70 is 7. 9 times ten percent of 70 (7) is 63. So 90 percent of 70 is 63.
7/9
90 + 7 is not and has never been equal to 70 + 9
I think you're referring to the notation for a repeating decimal.So it is 175.877777.... Well 0.777777.... is 7/9, and 0.87777 - 0.77777 = 0.1 = 1/10. so it is 175 + 7/9 + 1/10 which is 175 + 70/90 + 9/90 = 175 79/90
Since 90 degrees is pi/2 radians, 70 degrees would be (7/9*pi/2)=7pi/18 radians.
90/70 or 9/7
Ten percent of 70 is 7. 9 times ten percent of 70 (7) is 63. So 90 percent of 70 is 63.
7/9
7/9
7/9 = 70/90
7/9
facrtor both 90=2*3*3*5 70=2*5*7 2 and 5 are common to both so use once =2*3*3*5*7=630 check 630/9=7 630/7=9 7*2*5=70 9*2*5=90
9 tens is 90. 90 of 70 is 630.
90 + 7 is not and has never been equal to 70 + 9
7/9= 0.777... so no. ----------------------------------------------------------------- Alternatively, working with fractions: Convert to fractions with the same denominator and compare the numerators: 0.7 = 7/10 = (7×9)/(10×9) = 63/90 7/9 = (7×10)/(9×10) = 70/90 70 > 63 → 70/90 > 63/90 → 7/9 > 0.7 → No, 0.7 is less than 7/9 Instead of converting to equivalent fractions with the same denominator to compare numerators, if (and only if) the numerators are the same, the fractions can be compared by comparing the denominators and the fraction with the larger denominator is the smaller fraction: 0.7 = 7/10 7/9 same numerators, so compare denominators: 10 > 9 → 7/10 < 7/9 → 0.7 < 7/9 → No, 0.7 is less than 7/9
7 over 9 is equal to 14 over 18 and 70 over 90
40 to 90 = 4 to 9
