98*63 = (100-2)*(60+3) = 100*(60+3) - 2*(60+3)
= 100*60 + 100*3 - 2*60 - 2*3
= 6000 + 300 - 120 - 6
= 6174
The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. In this case, 98 x 7 can be calculated using the distributive property as 98 x 7 = 98 x (5 + 2) = (98 x 5) + (98 x 2) = 490 + 196 = 686. So, the distributive property helps break down the multiplication into simpler calculations.
To multiply 127 by 98 using mental math, you can use the distributive property. First, recognize that 98 is 100 - 2. Therefore, you can calculate (127 \times 98) as (127 \times (100 - 2) = 12700 - 254). This simplifies to (12700 - 254 = 12446), giving you the correct answer.
98/126 = 49/63 = 7/9
945 ÷ 98 = 9 with remainder 63 or 9.64 times.
