Here, we have to rounded up to nearest number then divide on our mind and estimate the quotient. When we divide by a two digit number it will be useful to estimate the quotient first. Example:- Consider, 52 ÷ 16 For this example. We have to round the number to nearest tens then estimate the quotient. So, 16 will be 20 and 52 will be 50 . As both side contains 0 , we can ignore this and then divide 5 ÷ 2 = 2 . Here the estimated quotient is 2 . When we estimate the quotient, ignore the remainder. Now, 52 ÷ 16 = 50 ÷ 20 Now, by following method we can fill the table: Division Sum Rounded Sum Think Estimated Quotient (a) 28 81 30 80 3 8 2 (b) 54 93 50 90 5 9 1 (c) 19 78 20 80 2 8 4 (d) 54 312 50 370 5 31 6 (e) 45 373 50 370 5 37 7 (f) 81 528 80 530 8 53 6 (g) 72 284 70 280 7 28 4 (h) 33 679 30 700 3 70 23 (i) 56 891 60 890 6 89 14 (j) 28 501 30 500 3 50 16 Hence, the answer table is given above.

Find the quotient and remainder. 91 ÷ 13

The given number 91 has to be divided by 13 . We know that, Dividend is the number to be divided and divisor is the number by which we are dividing. Quotient is the answer and remainder is the number left over. Divisor = 13 Dividend = 91 From the multiplication table of 13 , 13 × 7 = 91 7 13 9 1 - 9 1 0 Therefore, the quotient is 7 and remainder is 0 .

Find the quotient and remainder. 81 ÷ 28

The given number 81 has to be divided by 28 . We know that, Dividend is the number to be divided and divisor is the number by which we are dividing. Quotient is the answer and remainder is the number left over. Divisor = 28 Dividend = 81 From the multiplication table of 28 , 28 × 2 = 56 2 28 8 1 - 5 6 2 5 Therefore, the quotient is 2 and remainder is 25 .

Find the quotient and remainder. 94 ÷ 39

The given number 94 has to be divided by 39 . We know that, Dividend is the number to be divided and divisor is the number by which we are dividing. Quotient is the answer and remainder is the number left over. Divisor = 39 Dividend = 94 From the multiplication table of 39 , 39 × 2 = 78 2 39 9 4 - 7 8 1 6 Therefore, the quotient is 2 and remainder is 16 .
