Harriet Tubman's birthname was Araminta Ross. At a young age of 11, she was hired out as nursemaid for a small baby. She had to stay awake all night to make sure that the baby would not cry. She got the scar on her head when she refused to help in the punishment of another young slave.

A box contains 1079 counters which are coloured either black, white or red.

aleksley [76]

The total number of red counters that are in the box is; 728 red counters

We are told that the box contains 1079 counters.

Let the number of white counters be x.

Let the number of red counters be y.

Let the number of black counters be z.

Thus;

z:x = 2:7

Thus; 2x/7 = z

Also, we are given;

x:y = 3:8

Thus;

8x/3 = y

Since total number in the box is 1079,then;

x + y + z = 1079

x + (8x/3) + (2x/7) = 1079

Multiply through by 21 to get;

21x + 56x + 6x = 22659

83x = 22659

x = 22659/83

x = 273

2x/7 = z

Thus; z = 2 × 273/7

z = 78

8x/3 = y

y = 8 × 273/3

y = 728

Thus,there are;

273 white counters

728 red counters

78 black counters.
