b. 8.651 + 6.525 =                   h. 6.806 + 1.307 =                

c. 1.734 + 2.364 =                   i. 1.007 + 2.692 =                

d. 6.644 + 8.525 =                   j. 1.156 + 3.772 =                

e. 9.463 + 4.979 =                   k. 0.832 + 3.068 =                

f. 0.348 + 1.95 =                

  1. Subtract the following decimals:

a. 0.212 − 0.0923 =                   g. 8.9321 − 8.6884 =                

b. 7.9424 − 7.2035 =                   h. 1.1393 − 0.1102 =                

c. 9.3949 − 0.7979 =                   i. 1.2037 − 0.8918 =                

d. 6.2772 − 3.219 =                   j. 7.7646 − 1.4895 =                

e. 5.554 − 3.6097 =                   k. 4.1128 − 1.5693 =                

f. 2.2019 − 1.5055 =                

  1. Multiply the following decimals:

a. 7.5 × 5,311.4 =                   g. 1,427.47 × 14.54 =                

b. 289.5 × 48,960.6 =                   h. 44.99 × 55.5 =                

c. 6.402 × 51.9 =                   i. 30.9 × 0.2 =                

d. 84.144 × 0.378 =                   j. 9,419.4 × 6.1 =                

e. 0.075 × 77.64 =                   k. 9.92 × 4,621.6 =                

f. 0.436 × 8.867 =                

  1. Divide the following decimals:

a. 0.2107 ÷ 0.43 =                   g. 548.2681 ÷ 39.19 =                

b. 0.0064 ÷ 0.32 =                   h. 2,659.1408 ÷ 88.52 =                

c. 0.1218 ÷ 0.21 =                    i. 2,392.4077 ÷ 43.97 =                

d. 0.0693 ÷ 0.63 =                   j. 3,931.9881 ÷ 42.43 =                

e. 3,574.7888 ÷ 40.48 =                   k. 0.2132 ÷ 0.82 =                

f. 772.3285 ÷ 54.97 =
