Multiply it by 100: 17/40 times 100 = 42.5%
To add ( \frac{7}{8} ) and ( \frac{7}{10} ), first find a common denominator, which is 40. Convert the fractions: ( \frac{7}{8} = \frac{35}{40} ) and ( \frac{7}{10} = \frac{28}{40} ). Now, add them together: ( \frac{35}{40} + \frac{28}{40} = \frac{63}{40} ), which can also be expressed as ( 1 \frac{23}{40} ).
17 over 40 as a percentage = 42.5%% rate:= 17/40 * 100%= 0.425 * 100%= 42.5%
17/(40) = 42.5%
To simplify the fraction ( \frac{10}{40} ), you divide both the numerator and the denominator by their greatest common divisor, which is 10. This gives you ( \frac{10 \div 10}{40 \div 10} = \frac{1}{4} ). Therefore, ( \frac{10}{40} ) simplified is ( \frac{1}{4} ).
To calculate ( \frac{3}{5} \times \frac{3}{8} ), you multiply the numerators and the denominators: ( \frac{3 \times 3}{5 \times 8} = \frac{9}{40} ). Therefore, ( \frac{3}{5} \times \frac{3}{8} = \frac{9}{40} ).
To add ( \frac{7}{8} ) and ( \frac{7}{10} ), first find a common denominator, which is 40. Convert the fractions: ( \frac{7}{8} = \frac{35}{40} ) and ( \frac{7}{10} = \frac{28}{40} ). Now, add them together: ( \frac{35}{40} + \frac{28}{40} = \frac{63}{40} ), which can also be expressed as ( 1 \frac{23}{40} ).
17 over 40 as a percentage = 42.5%% rate:= 17/40 * 100%= 0.425 * 100%= 42.5%
17/(40) = 42.5%
To simplify the fraction ( \frac{10}{40} ), you divide both the numerator and the denominator by their greatest common divisor, which is 10. This gives you ( \frac{10 \div 10}{40 \div 10} = \frac{1}{4} ). Therefore, ( \frac{10}{40} ) simplified is ( \frac{1}{4} ).
To calculate ( \frac{3}{5} \times \frac{3}{8} ), you multiply the numerators and the denominators: ( \frac{3 \times 3}{5 \times 8} = \frac{9}{40} ). Therefore, ( \frac{3}{5} \times \frac{3}{8} = \frac{9}{40} ).
To find the percentage of incorrect answers, divide the number of wrong answers by the total number of questions and then multiply by 100. So, ( \frac{13}{40} \times 100 = 32.5% ). Therefore, 32.5% of the answers are wrong.
To divide 2.6 by 4, you can express 2.6 as a fraction: ( 2.6 = \frac{26}{10} ). Dividing by 4 gives you ( \frac{26}{10} \div 4 = \frac{26}{10} \times \frac{1}{4} = \frac{26}{40} ). Simplifying ( \frac{26}{40} ) results in ( \frac{13}{20} ), which is equal to 0.65 when converted to decimal form. Thus, 2.6 divided by 4 equals 0.65.
Two-fifths can be represented as the fraction ( \frac{2}{5} ) and as a decimal, which is 0.4. Additionally, it can be expressed as a percentage, equal to 40%.
percentage = 42.5%% rate:= 17/40 * 100%= 0.425 * 100%= 42.5%
23/40 = 57.5 %
To solve (4 \frac{3}{8} \times \frac{4}{5}), first convert the mixed number to an improper fraction: (4 \frac{3}{8} = \frac{35}{8}). Then, multiply: [ \frac{35}{8} \times \frac{4}{5} = \frac{35 \times 4}{8 \times 5} = \frac{140}{40} = \frac{7}{2} = 3 \frac{1}{2}. ] Therefore, the answer is (3 \frac{1}{2}).
To express 0.075 in its simplest form as a fraction, first recognize that it can be written as ( \frac{75}{1000} ). To simplify, divide both the numerator and denominator by their greatest common divisor, which is 25. This results in ( \frac{3}{40} ), so 0.075 in its simplest form is ( \frac{3}{40} ).
