When working with mixed numbers, it is usually easier to convert them to improper fractions, do the operations, and then to convert any resulting improper fraction back to a mixed number: 1 1/4 + 2 3/20 + 3/5 = (1×4+1)/4 + (2×20+3)/20 + 3/5 = 5/4 + 43/20 + 3/5 = (5×5)/(4×5) + 43/20 + (3×4)/(5×4) = 25/20 + 43/20 + 12/20 = (25+43+12)/20 = 80/20 = 4
43=40+3=40+3/1
When adding or subtracting fractions where the denominators are different. Convert the fractions to a common denominator. Sometimes it is possible to operate on the integers separately to the fraction part but it is good practice to convert mixed numbers into improper fractions. 3²/₅ - 1¼ = 17/5 - 5/4 The common denominator of 5 and 4 is 20. (4 x 17) - (5 x 5) ÷ 20 = (68 - 25) ÷ 20 = 43/20 This can be converted to the mixed number 2 and 3/20
43% of 20= 43% * 20= 0.43 * 20= 8.6
Improper fractions, like 43/8, can become mixed numbers like 5 and 3/8, but they cannot become proper fractions.
43% of 20 is 8.6
20% of 43 = 8.6 = 20% * 43 = 20%/100% * 43 = 86/10 or 8.6
The LCM of 20, 43 is 860.
43 multiplied by 20 is 860.
