Find the difference in length between a walking stick and a bumblebee PLS HELP HURRY​
Tanya [424]

Difference between the lengths of walking stick and lengths of bumble bee is 3\frac{4}{8} inch.

Solution:

Given data represents the length of the insects.

Length of the walking stick = 4 in

Length of the bumble bee = \frac{5}{8} in

Difference between their length

                                        $=4-\frac{5}{8}

                                        $=\frac{4}{1} -\frac{5}{8}

To make the denominator same, multiply and divide the first term by 8.

                                        $=\frac{32}{8} -\frac{5}{8}

                                        $=\frac{32-5}{8}

                                        $=\frac{27}{8}

Now, change improper fraction into mixed fraction, we get

                                         $=3\frac{4}{8}

Difference between the lengths of walking stick and lengths of bumble bee is 3\frac{4}{8} inch.
