To convert a percent to a decimal, move the decimal point two places to the left. To convert a decimal to a percent, move the decimal point two places to the right. When a decimal number repeats, place a bar above the repeating number(s). To write a decimal as a fraction, write or say the number with place value. Simplify the fraction by dividing the numerator and denominator by the GCF. To convert a mixed number to a decimal, make the fraction improper. Divide the bottom number into the top number. Percent means “out of a hundred.” Absolute value is how far a number is from zero. 1) Write 3/5 as a decimal. 2) Write 6/9 as a decimal. 3) Write 340% as a decimal. 4) Write 0.03% as a decimal. 5) Write 45% as a decimal. 6) Write 0.08 as a fraction in simplest form. 7) Write – 2/5 as a decimal number. 8) Write –2 3/4 as a decimal number. 9) Write the number -0.45 as a fraction in simplest form. 10) Write the decimal number -3.2 as a mixed number in simplest form. 11) Mr. Mean’s class is 55% boys.
