Answer

21.8 yd

Work Step by Step

20 m to yards We’re changing from a metric length unit to a U.S. length unit. In the “Metric to U.S. Units” side of the table, you see that 1 meter = 1.09 yards. Two unit fractions can be written using that information.(1 m)/(1.09 yd) Or(1.09 yd)/(1 m). Multiply by the unit fraction that allows you to divide out meters (that is, meters is in the denominator). 20 m * (1.09 yd)/(1 m) = 21.8 yd
