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

Answer:

a)  $1\frac{1}{4}+68\%+0.7=2.63$

b) $\frac{3}{8}+0.42+13.5\%=0.93$

Step-by-step explanation:

To find : Add the following ?

Solution :

a) $1\frac{1}{4}+68\%+0.7$

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

$1\frac{1}{4}=\frac{5}{4}=1.25$

$68\%=\frac{68}{100}=0.68$

Substitute back,

$1\frac{1}{4}+68\%+0.7=1.25+0.68+0.7$

$1\frac{1}{4}+68\%+0.7=2.63$

b) $\frac{3}{8}+0.42+13.5\%$

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

$\frac{3}{8}=0.375$

$13.5\%=\frac{13.5}{100}=0.135$

Substitute back,

$\frac{3}{8}+0.42+13.5\%=0.375+0.42+0.135$

$\frac{3}{8}+0.42+13.5\%=0.93$
