Please help me i need to do my son homework for tommorow!!!!!

[Suz855]

Choose 4x6 = 24 rectangles


To add or subtract fraction with fraction, its denominator has to be the same

1/3 in this case, you will shade 8 rectangle
5/12, 10 rectangles

in all 18 rectangles will be shade and it will show 3/4 of the total figures shaded … good luck

I am a 4-digit number.

The digit in the thousands place makes 5 when added to 2.
The digit in the hundreds place stands for 400.
The digit in the tens place is the same as the digit in the thousands place.
The digit in the ones place is the smallest possible digit.

What number am I?

Child's answer is 3431. Answer key is 3430.

Question 1: Is 'zero' consider a digit?

Question 2: Hypothetically, if the last statement is rephrase as 'The digit in the ones place has the smallest possible value', will it be 'one' or 'zero'?

TIA.

Hello again!

New question...is zero considered a digit? I think so, but there has

I certainly do appreciate all your help!

Hello!

Yes, zero is a digit. It's a really really important digit! A digit is
anything that you can write down in your expression of a number in
regular notation. So since zero shows up in numbers like 307, and 10,
and even 0, zero is a digit.

Hi,

Jo [][][][]
Je []


Jo [][][][][-$240-] = [][$180][][$180]
Je [][$180]

2 u + 240 --> 180 x 2
2 u --> 120
1u --> 120/2 = 60

5 u --> 5 x 60 = $300

They had altogether $300 at first.
