Transforming a Fraction from Mixed to Improper
= (c×A)+bc First, list down the known values.Total number of apples=27Percentage of red apples=6623%Next, change the percentage into an improper fraction by multiplying the denominator by the whole number and then adding the numerator6623 = (3×66)+23 = 198+23 = 2003% Then, convert the percentage to a fraction by having 100 as the percentage value’s denominatorDividing fractions is the same as multiplying the dividend by the divisor’s reciprocalFraction = 2003100 = 2003÷100 Change from a fraction to division = 2003×1100 Get the divisor’s reciprocal then multiply = 23 Simplify Finally, to get the percentage of an amount, simply solve for their product. Use fractions for easier computation.23×27 = 23×271 Convert values to fraction form = 21×91 Simplify = 181 = 18 Hence, there are 18red apples_.To solve for number of green apples, subtract the number of red apples from the total number of applesGreen apples = 27−18 = 9 9 green apples -

A commission is expressed as a percentage of the value of goods sold.First, draw a line diagram to further understand the given values.Solve for the remaining balance by subtracting $80,000 from the value of the house, which is $420,000.Remaining Balance = $420,000−80,000 = $340,000 Next, solve the commission for the first $80,000 of the value, which will be 3.5%.$3.5%×80,000 = 3.5100×80,0001 Convert values to fraction form = $0.035×80,000 Simplify = $2800 Then, solve the commission for the rest of the value, which will be 2%.$2%×340,000 = 2100×340,0001 Convert values to fraction form = $0.02×340,000 Simplify = $6800 Finally, add the two commissions to get the total commissionTotal Commission = 2800+6800 = $9600 Hence, the real estate agent will get a total commission of $9600_.$9600 -
