Answer:
Step-by-step explanation:
Length of a pair of skis = 6 feet 11 inches
Maximum length of a the skis that can be fitted in a wardrobe is along the diagonal of the wardrobe.
From the picture attached,
BC² = 3² + 2² [By Pythagoras theorem]
BC = √(13)
By applying Pythagoras theorem in ΔABC,
AB² = AC² + BC²
AB² = 6² + (√13)²
= 36 + 13
AB = √49
Ab = 7 feet
Since, "diagonal length of the wardrobe is more than the length of skis,
skis can be fitted"
To write 9 as 63, you need to multiply it by a number. 63/9 = 7.
So you need to multiply 9 by 7 to get 63.
But since it's a fraction, you can't multiply the denominator without multiply the numerator. So you need to multiply the denominator, 9, by 7 and the numerator, 8, by 7.
8/9 = (8*7) / (9*7) = 56/63
So 8/9 = 56/63
Hope this helps! :)
