Question

1 và  4 phần 7 × 3 và 4 phần 11 × 3 và 11 phần 15 × 5 và 5phần 8

Answer 1

`1 4/7 xx 3 4/11 xx 3 11/15 xx 5 5/8`

`= 11/7 xx 37/11 xx 56/15 xx 45/8`

`=111`

Answer 2

\(1\dfrac{4}{7}\cdot3\dfrac{4}{11}\cdot3\dfrac{11}{15}\cdot5\dfrac{5}{8}=\dfrac{11}{7}\cdot\dfrac{37}{11}\cdot\dfrac{56}{15}\cdot\dfrac{45}{8}=111\)

Answer 3

=\(\dfrac{11}{7}\)x\(\dfrac{37}{11}\)x\(\dfrac{56}{15}\)x\(\dfrac{45}{8}\)

=\(\dfrac{37}{7}\)x21

= 111

Answer 4

$1\frac{4}{7}\times 3\frac{4}{11}\times 3\frac{11}{15}\times 5\frac{5}{8}$

$=\frac{11}{7}\times \frac{37}{11}\times \frac{56}{15}\times \frac{45}{8}$

$=\mathrm{11x37x56x45}$_/7x11x15x8
