Please help me with this question!

Answer 1

`\text {Laura = } 12 \text { years } 3 \text { months }`


`\text {Lisa = } 11 \text { years } 7 \text { months }`


`\text {Deborah = } 11 (1)/(2) \text { years } = 11 \text { years } 6 \text { months }`


`\text {Elizabeth = } 11 (1)/(3) \text { years } = 11 \text { years } 4 \text { months }`

-----------------------------------------------------
Find Total :
-----------------------------------------------------

`\text {Total = } 12 \text { yr } 3 \text { mth } + 11 \text { yr } 7 \text { mth } + 11 \text { yr} 6 \text { mth} +11 \text { yr } 4 \text { mth}`


`\text {Total = } 45 \text { years } 20 \text { months }`

-----------------------------------------------------
Find Average :
-----------------------------------------------------

`\text {Average = } (45 \text { years } 20 \text { months }) / 4`


`\text {Average = } 560 \text { months } / 4`


`\text {Average = } 140 \text { months } / 4`


`\text {Average = } 11 \text { years } 8 \text { months }`

----------------------------------------------------------------------------------------------------------

`\bf \text {Answer : Average = } 11 \text { years } 8 \text { months }`
