Question

*Amit ordered a cake. He divided the cake in 4 parts of different size. If the three parts are 1/2, 1/4 and 1/8, then find the forth part of the cake.*

Answer 1

Answer:

✡ 1/8 ☑

Step-by-step explanation:

Given ⤵

• Amit ordered a cake.
• He divided the cake in 4 parts of different size.
• If the three parts are 1/2, 1/4 and 1/8.

To find⤵

• Fourth part of the cake.

Solution⤵

⚫Firstly we have to add three part of cake.

$➡ \frac{1}{2} + \frac{1}{4} + \frac{1}{8} \\ ➡ \frac{(1 \times 4)}{(2 \times 4)} + \frac{(1 \times 2)}{(4 \times 8)} + \frac{1}{8} \\ ➡ \frac{4 + 2 + 1}{8} \\ ➡ \frac{7}{8}$

⚫To obtaining forth part we have to subtract sum of three part in total cake.

⚫Total cake is one. Sum of three part of cake is 7/8.

$➡1 - \frac{7}{8} \\ ➡ \frac{(1 \times 8)}{(1 \times 8)} - \frac{7}{8} \\ ➡ \frac{8 - 7}{8} \\➡ \frac{1}{8}$

$✅Hence,\:fourth\: part\: is\: \frac{1}{8}.$
