Question

Please help not sure on this one thank you

Answer 1

12 inches in a foot so 1.8×12= 21.6 inches
2.54cm in one inch so 56/2.54=22.04inches
and 20inches=20 inches

so in greatest to last order the numbers would be
56cm > 1.8ft > 20inches

Answer 2

I would convert everything to cm

20 inches: 20*2.54=50.8 cm
1.8 ft: 1.8*12 = 21.6 in, 21.6*2.54 = 54.864 cm

So then we know 20 inches in least, followed by 1.8 feet, followed by 56 cm

Hope this helps
