Answer:
4.43
Step-by-step explanation:
7.90
- 3.47
__________
4. 4 3
I couldn't regroup but of you cross out 0 and put 10, 10-7= 3
and you have to borrow one from 9 and make it 8 and 8-4=4
The answer would be 81.2 because all you gotta do it 20.3 times 4
Find 1 1/4 on the number line and count back 3/4 (why it is negative) answer is 1/2.
Divide I from both sides then subtract r from both sides, too so in the end:
R= (E-r)/I
It can go into 192 7.1 times
