0.47 is greater than six thirteenths.

Work (two ways you can do it by hand):

1) Change the fraction to a decimal:
6 ÷ 13 = 0.461538461538... (repeating). Since 0.47 = 0.470000..., 0.470000... > 0.461538..., so 0.47 > 6/13.

2) Or change the decimal to a fraction and cross-multiply:
0.47 = 47/100. Compare 47/100 and 6/13 by cross-multiplying:
47 × 13 = 611, and 6 × 100 = 600. Because 611 > 600, 47/100 > 6/13.

Which I prefer: convert the decimal to a fraction (when the decimal terminates), then cross-multiply. It’s usually faster and exact, avoiding long division. Converting the fraction to a decimal is fine when the denominator divides nicely.
