Answer:
Step-by-step explanation:
15×20+15×x
= 0.8333....
<u>Step-by-step explanation:</u>
Here 6 is the divisor and 5 is the dividend, and 5 is lesser than 6, so in the quotient we have to put 0 then a decimal point and 0 along with 5, so the dividend becomes 50, 8 times 6 is 48, 50 - 48 = 2, then add one more 0 with 2, so it becomes 20, 3 times 6 is 18 again, 2 is the remainder and this process is going on. So the quotient is 0.8333...
So
= 0.8333....
33 rounds to 30 and 89 rounds to 80. 80 x 30= 2400
Like your writing, but what exactly is it??
