Hey, expressing 59.2475 would look like:
Word form: Fifty-nine and two thousand, four hundred seventy-five ten-thousandths.
Expanded Notation Form:
50 + 9 + 0.2 + 0.04 + 0.007 + 0.0005.
If there are 27 students in the class and they have to form as many groups of 4 as possible, you can calculate this using the following step:
27 / 4 = 6.75 = 6 3/4
Result: 27 students can form 6 groups of 4 students and 3 students have to form their own group.
15 divided by 3 is 5
15 - 3=13
Answer is 1704 and to explain just put that you added to get your final answer
