(b) 3/16

Step-by-step explanation:

Let the area of the large triangle be 1

The area of one smaller triangle out of the 4 is 1/4*1

= 1/4

So the area of the middle triangle of the larger one is 1/4..

This has been further divided into 4 triangles

The area of one such triangle is one quarter of 1/4

= 1/4 * 1/4

= 1/16

So we can infer that the area of one shaded triangle is 1/16

It asks for the area of all 3 shaded triangles

= 3 * 1/16

= 3/16

So the area of the large triangle that has been shaded is 3/16.

Hope it helps!

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

93-8=85

855=17

17*4=68

there are 68 purple marbles in that bag
