Yesterday, Ian walked 2/3 of a mile. Today, he walked 1/5 of a mile. How far did he walk altogether?

13/15 miles

Step-by-step explanation:

2/3 = 10/15

1/5= 3/15

10/15 + 3/15 = 13/15.

1.4km

Step-by-step explanation:

2/3 + 1/5

Find the LCM of the denominators

(5x2)+(3x1)/15

Clear brackets:

5x2=10

3×1=3

Therefore, we have

10+3/15=13/15

In total, he has walked 13/15 of a mile

1 mile is 1.609344 km

Therfore, he walked 13/15×1.609344 km=1.4km approximately.

OR

2/3 of 1mile is 2/3×1.609344 km

=1.07km

1/5 of 1 mile the next day is 1/5×1.609344 km

=0.32km

Total distance 1.07+0.32=1.39 approximately 1.4km

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
