The 2003 is (2 * 2003-1) / (3 * 2003)

-4 and 7 / 8 - (+ 4 and 1 / 4) - (- 5 and 1 / 2) + (- 3 and 1 / 8)

-4 and 7 / 8 - (+ 4 and 1 / 4) - (- 5 and 1 / 2) + (- 3 and 1 / 8)
=[- 4 and 7 / 8-3 and 1 / 8] - (4 + 1 / 4) + (5 + 1 / 2)
=-8+（-4+5）+（-1/4+1/2）
=-8+1+1/4
=-7+1/4
=-6 and 3 / 4

Two and a half, four and an eighth, six and an eighth, eight and a sixteenth, (?)
I know the answer, but what about the process?

15 out of 65 and 4 out of 13

1. 15 / 65 can be simplified to 3 / 13, which is also a full score
2. Change the numerator 4 / 13 and denominator * 5 to 20 / 65. This is also a general division

13 out of 15 and 4 out of 45

39／45,4／45

Compare the numbers of the following groups and explain the reasons 13 / 7 and 11 / 5, 15 / 1 and 29 / 2, 12 / 11 and 15 / 14, 2 / 1 and 9 / 5
"/ 'denotes a fractional line

There are many ways to compare the size of fractions. If the product of the numerator of the first fraction × the denominator of the second fraction is larger than the product of the numerator of the first fraction × the numerator of the second fraction, the first fraction will be larger than the second fraction, otherwise it will be smaller. 13 / 7 and 11 / 5 15 /

One twelfth plus one fourth times seven sixths minus three eighths

Let's start with multiplication. One fourth multiplied by seven sixths equals seven twenty-four, nine twenty-four plus one twelfth equals nine twenty-four, nine twenty-four minus three eighths equals zero

Seven eighths minus one twelfth plus one sixth
