Calculations

a) 2/3 + 2/9 = To solve this, we can find a common denominator and then add the fractions together. The sum of 2/3 and 2/9 is 8/9.

b) 23/30 - 11/20 = To subtract these fractions, we need to find a common denominator and then subtract the second fraction from the first. The difference between 23/30 and 11/20 is 1/60.

c) 5/8 * 7/5 = To multiply these fractions, we simply multiply the numerators together and the denominators together. The product of 5/8 and 7/5 is 7/8.

d) 4/25 ÷ 8/5 = To divide these fractions, we can multiply the first fraction by the reciprocal of the second fraction. The quotient of 4/25 and 8/5 is 1/10.

e) 3 3/5 + 2 1/3 = To add these mixed numbers, we first convert them to improper fractions, then add them together and simplify the result. The sum of 3 3/5 and 2 1/3 is 5 4/15.

f) 6 1/2 - 4 2/3 = To subtract these mixed numbers, we first convert them to improper fractions, then subtract the second fraction from the first and simplify the result. The difference between 6 1/2 and 4 2/3 is 1 5/6.

g) 3 3/8 * 4 = To multiply a mixed number by a whole number, we first convert the mixed number to an improper fraction, then multiply it by the whole number. The product of 3 3/8 and 4 is 13 1/2.

h) 5 3/7 ÷ 19 = To divide a mixed number by a whole number, we first convert the mixed number to an improper fraction, then divide it by the whole number. The quotient of 5 3/7 and 19 is 28/19.

i) 27 * (1/3 - 4/9 - 5/27) = To solve this expression, we first simplify the expression inside the parentheses, then multiply the result by 27. The value of 27 * (1/3 - 4/9 - 5/27) is 6.
