ii) The ratio of children who went for the picnic to the children who did not go for the picnic.
iii) The ratio of total children to the number of boys who went for the picnic.
iv) The ratio of total children to the number of gals who went for the picnic.
v) Which ratio is greater among part (ii) and part (iii)?

Answer 1

Currently, agriculture is divided into two different types, including industrialized agriculture and subsistence agriculture. Let's explore and learn more about these two types of agriculture.

Answer 2

It is given that from a group of 25 children, 10 boys and 5 gals went for a picnic.

i) Number of children who did not go for the picnic.

Total number of children who went for the picnic = 10 + 5 = 15

Number of children who did not go for the picnic = 25 - 15 = 10

ii) The ratio of children who went for the picnic to the children who did not go for the picnic.

Number of children who went for the picnic = 15

Number of children who did not go for the picnic = 10

Ratio = 15/10 = 3:2

iii) The ratio of total children to the number of boys who went for the picnic.

Number of boys who went for picnic = 10 boys

Ratio = 25/10 = 5:2

iv) The ratio of total children to the number of gals who went for the picnic.

Number of gals who went for the picnic = 5

Ratio = 25/5 = 5:1

v) Which ratio is greater among part (ii) and part (iii)?

Ratio of part (ii)  = 3:2

Ratio of  part (iii) = 5:2

Therefore among part (ii) and part (iii), part (iii) has the higher ratio.
