A number without denominator such is equal to number with denominator 1.
So, 24 is equal to 24/1
5/8 x 24
= 5/8 x 24/1
= (5x24) / (8x1)
= 120/8
= 15
(1) 2800 - 15% of 2800 =
2800 - 0.15(2800) =
2800 - 420 = 2380
(2) if he is reducing it by 15%, then he is actually eating 85%....
0.85(2800) = 2380
Value x as the weight of the large box, y as the weight of the small box
7x + 9y = 157 (1)
5x + 3y = 89 -> 15x + 9y = 267 (2)
(2) - (1) => 8x = 110
=> x = 13.75 kg
=> (1) => 5x13.75 + 3y = 89 => 3y = 20.25 => y = 6.75 kg
So, large box weigh 13.75 kg, and small box weigh 6.75 kg
Mark Brainliest if correct. :D
