RS Aggarwal Vikash Aggarwal Class 4 Activity Book Composite Mathematics Activity Sheet 53 SolutionActivity Sheet – 53Round each factor with more than one digit to the nearest ten. Then estimate the product.Estimate the product by rounding to the nearest hundred:Estimate the product to the nearest ten by rounding the first factor up and the second factor down:Estimate the product to the nearest hundred by rounding the first factor up and the second factor down:
(2) 49 x 6 = 50 x 6 = 300
(3) 57 x 31 = 60 x 30 = 1800
(4) 62 x 88 = 60 x 90 = 5400
Estimate the product by rounding to the nearest hundred:
(5) 634 x 459 = 600 x 500 = 300000
(6) 324 x 812 = 300 x 800 = 24000
(7) 254 x 748 = 300 x 800 = 210000
(8) 489 x 896 = 500 x 900 = 450000
Estimate the product to the nearest ten by rounding the first factor up and the second factor down:
(9) 47 x 88 = 50 x 80 = 4000
(10) 64 x 46 = 70 x 40 = 2800
Estimate the product to the nearest hundred by rounding the first factor up and the second factor down:
(11) 452 x 768 = 500 x 700 = 350000
(12) 283 x 536 = 300 x 500 = 150000
