Answer:
Ok so here are the explanation for 24 - 30
24. = 10 2/4 - 5 1/3
= (10-5)+( 2/4 - 1/3)
= 5 + ( 2×3) 1×4
( 4×3). 3×4
= 5 + 6/12 - 4/12
= 5+ 6 - 4
12
= 5 + 2/12
= 5+ 2 ÷ 2
12 ÷2
Answer = 5 1/6
25. = 5/15+5/9
= 5×3 + 5×5
15×3. 9×5
= 15/45 + 25/45
= 15 + 25
45
= 40/45
= 40÷5
Answer = 8/9
45÷5
26. = 3/9 + 7/7
= 3 × 7 + 7 × 9
9 × 7. 7 × 9
= 21. +. 63
63. 63
= 21 + 63
63
= 84
= 84 ÷ 21
63 ÷ 21
= 4/3
= 1 and 1/3
27. = 2 3/6 × 2/5
= 15 × 2/5
6
= 15 × 2
6 × 5
= 30
30
Answer= 1
28. = 10× 2/8
= 10 × 2
1 × 8
= 20/8
= 20 ÷ 4
8 ÷ 4
= 5
2
= 2 1/2
29. = 1/3 ÷ 5 2/4
= 1/3 ÷ 22/4
= 1/3 × 4/22
= 1 × 4
3×22
=4/66
= 4 ÷ 2
66÷2
Answer = 2/33
30. = 3/9 ÷ 21
= 3/9 × 1/21
= 3 × 1
9×21
= 3/189
= 3 ÷ 3
189÷3
= 1/63
:O there you go
After my hard work HEHE
thx hope it helps<3
