A large square is divided into 4 smaller squares; then small left square is divided into 4 smaller squares as well. What fraction of the large square is
shaded?

OPTIONS

4 over 5
3 over 8
4 over 9
1 over 3
1 over 2​

The total fraction shaded is 1/2

Step-by-step explanation:

Here, we want to know the fraction shaded

As we can see, the box is originally divided into 4

So each of the 4 parts are 1/4

for the first part, we have 4 divisions;

This means each of the divisions with respect to the whole fraction will be 1/4/4 = 1/16

Now, two of these are shaded, making 1/16 and 1/16

Secondly, we have half of the 1/4 : So with respect to the whole, we have 1/4/2 = 1/8

for the third part, the whole 1/4 is shaded

and lastly, we have an unshaded 1/4

so, the total fraction shaded will be ;

1/16 + 1/16 + 1/4 + 1/8

= (1 + 1 + 4 + 2)/16 = 8/16 = 1/2

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
