Question

- 35. Select values of m, n to make the statement true. 127 x 15 = mx 15) + (n x 15) ( (1) m = 100, n = 15 (2) m = 120, n = 15 (3) m = 15, n = 27 (4) m = 100, n = 27​

Answer 1

Answer:

m = 100, n = 27​ is correct for 127 x 15 = (mx 15) + (n x 15)

Step-by-step explanation:

Identity:

(a + b)xc= ac + bc

127 x 15 = (mx 15) + (n x 15)

Here (a + b) = (m + n)

m + n = 127

1) m = 100 and n= 15

m + n = 100 + 15

=115 ≠127

2) m = 120 and n= 15

m + n = 120 + 15

=135 ≠127

3) m = 15 and n= 27

m + n = 27 + 15

=42 ≠127

4) m = 100 and n= 27

m + n = 100 + 27

=127

So, m = 100 and n= 27 are the values of m and n.

Answer 2

Answer:

ans ( 4)

Step-by-step explanation:

127×15=m×15+(n×15)

1905=(m×15)+(n×15)

1905=(100×15)+(27×15)

1905=1905

hence , proved that 127×15=(100×15)+(27×15)
