The corresponding estimate for numbers in 1,2,3 and 4 are 10, 24, 21 and 153How to estimate numbers?Estimation and approximation is the process of using rounded values when presenting numerical data and making rough calculations.The digits 1,2,3 and are rounded down and digits 5,6,7,8 and 9 are rounded up1. 2.1 x 5.12 = 2 x 5 = 10Explanation: The number after the digit 2 in 2.1 is 1, we will round down 2.1 to 2. Also, the number after the digit 5 in 5.12 is 1, we will round down 5.12 to 52. 12.3 x 1.6 = 12 x 2 = 24Explanation: The number after the digit 12 in 12.3 is 3, we will round down 12.3 to 12. Also, the number after the digit 1 in 1.6 is 6, we will round up 1.6 to 23. 6.5 x 3.1 = 7 x 3 = 21Explanation: The number after the digit 6 in 6.5 is 5, we will round up 6.5 to 7. Also, the number after the digit 3 in 3.1 is 1, we will round down 3.1 to 34. 51.3 x 2.7 = 51 x 3 = 153Explanation: The number after the digit 51 in 51.3 is 3, we will round down 51.3 to 51. Also, the number after the digit 2 in 2.7 is 7, we will round up 2.7 to 3Therefore, the estimate for 1,2,3 and 4 are 10, 24, 21 and 153 respectivelyLearn more about estimation and approximation on:brainly.com/question/29033029#SPJ1
