Answer (1)
AnswerLet’s estimate the products by rounding each number to the nearest whole number and then multiplying:2.5 x 2.3:Round 2.5 to 3Round 2.3 to 2Estimated product: ( 3 \times 2 = 6 )3.2 x 7.6:Round 3.2 to 3Round 7.6 to 8Estimated product: ( 3 \times 8 = 24 )4.75 x 1.7:Round 4.75 to 5Round 1.7 to 2Estimated product: ( 5 \times 2 = 10 )6.63 x 2.5:Round 6.63 to 7Round 2.5 to 3Estimated product: ( 7 \times 3 = 21 )7.41 x 3.56:Round 7.41 to 7Round 3.56 to 4Estimated product: ( 7 \times 4 = 28 )8.32 x 4.64:Round 8.32 to 8Round 4.64 to 5Estimated product: ( 8 \times 5 = 40 ) 3.14 x 2.31:Round 3.14 to 3Round 2.31 to 2Estimated product: ( 3 \times 2 = 6 )5.41 x 3.61:Round 5.41 to 5Round 3.61 to 4Estimated product: ( 5 \times 4 = 20 )10.32 x 5.74:Round 10.32 to 10Round 5.74 to 6Estimated product: ( 10 \times 6 = 60 )12.02 x 4.84:Round 12.02 to 12Round 4.84 to 5Estimated product: ( 12 \times 5 = 60 )
