weight is?​

Answer 1

Answer:

The new weight of David after the reduction is 48 kg.

Step-by-step explanation:

Weight of David= 56 kg

Following the ratio of his weight loss, we can derive that-

The ratio of old weight: New weight= 7:6

Therefore, it can be said that 7 is equivalent to 56 kg

Hence, 6 is equivalent to = 48 kg

So, his new weight after the reduction is 48 kg.

Answer 2

Answer:

Step-by-step explanation:

Given,David weighs = 56 kg

Let, David new weigh = x kg

We have to distribute davit old weigh and new weighs in the ratio of 7:6

Now,

Davit new weighs = 6/13(56+x)

or x=6/13(56+x)

or 13x = 6*56+6x

or 13x-6x = 6*56

or 7x =6*56

or x = 6*8

Therefore, x = 48
