Yoshi wrote the standard form for three hundred sixty and nine hundred seven thousandths. This is the number 360.907. This number consists of 3 hunreds, 6 tens, 0 ones and 9 tenths, 0 hundredths, 7 thousandths.
Kim wrote a number with 3 more ones and 7 less tenths.
- Yoshi wrote 0 ones, then Kim wrote 0 + 3 = 3 ones;
- Yoshi wrote 9 tenths, then Kim wrote 9 - 7 = 2 tenths.
Actually Kim wrote 363.207 (see added place value table).
Answer: 363.207
Let width be x m
perimeter = 2L + 2W
W = x and L = 4W - 7 = 4x - 7
so we have the equation
2(4x - 7) + 2x = 136
8x - 14 + 2x = 136
10x = 150
x = 15
So the width = 15m and the length = 4(15) -7 = 53 m. Answer
