Question

10×3/23×10,10×2/21×30,4×5/15×16,8×9/27×16 сократите обыкновенные дроби HELLP

Answer 1

$frac{10 times 3}{23 times 10} = frac{3}{23 } \ frac{10 times 2}{21 times 30} = frac{2}{21 times 3} = frac{2}{63} \ frac{4 times 5}{15 times 16} = frac{1}{3 times 4} = frac{1}{12} \ frac{8 times 9}{27 times 16} = frac{1}{3 times 2} = frac{1}{6}$

Answer 2

1. 10× 3/23×10=10×3×10:23=300/23= 13 1/23
2. 10×2/21×30=10×2×30:21=600/21=28 12/21=
=28 4/7
3. 4×5/15×16,8×9/27×16=(16,8=16 4/5)=
4×5×84×9×16:15×5×27=5376/135=
=39 111/135
