a. 1¼ + 68% + 0.7 = Answer
b. 3/8 + 0.42 + 13.5% = Answer

Answer 1

1/4=0.25 0.25+1 =1.25
68/100= 0.68
1.25+0.68+0.7= 2.63




3/8= 0.375
13.5/100=0.135
0.375+0.42+0.135=0.93
sorry i took long

Answer 2

a)
`1(1)/(4)+68\%+0.7=2.63`

b)
`(3)/(8)+0.42+13.5\%=0.93`

Explanation:

To find : Add the following ?

Solution :

a)
`1(1)/(4)+68\%+0.7`

We solve each term in same form so that we easily add them,

`1(1)/(4)=(5)/(4)=1.25`

`68\%=(68)/(100)=0.68`

Substitute back,

`1(1)/(4)+68\%+0.7=1.25+0.68+0.7`

`1(1)/(4)+68\%+0.7=2.63`

b)
`(3)/(8)+0.42+13.5\%`

We solve each term in same form so that we easily add them,

`(3)/(8)=0.375`

`13.5\%=(13.5)/(100)=0.135`

Substitute back,

`(3)/(8)+0.42+13.5\%=0.375+0.42+0.135`

`(3)/(8)+0.42+13.5\%=0.93`
